The only review of a cohort house that means anything is the second booking.
A program can be polite about a mediocre summer. It will not spend its housing budget in the same place twice, because the person who chooses badly has to live with twelve people who know it. So the simplest way to describe how the Stanford Mayfield Fellows' first summer at hyperstay went is this: they came back the following year, and the second time they took an entire building.
This is a case study of both summers — what the program needed, what we did, what the fellows said afterwards, and what we would tell any other program director planning the same thing.
The program
The Mayfield Fellows Program is Stanford's flagship work-study program in building high-growth technology ventures, run by the Stanford Technology Ventures Program and founded in 1996. It is small and highly selective: 12 undergraduate and co-term students a year, from any major.
The structure is nine months across three quarters:
- Spring — ENGR 140A. Coursework in entrepreneurial leadership, cohort formation, and securing the summer internship.
- Summer — ENGR 140B. A paid, full-time internship at an early-stage startup in the San Francisco Bay Area, with a senior-level mentor inside the company, plus 1:1 mentorship from venture capital and alumni mentors, and cohort reflection sessions.
- Autumn — ENGR 140C. Capstone case studies, teaching one another, reflection.
One of the fellows put the summer better than any brochure. In a testimonial on our homepage, Andreas Lorgen wrote:
The Mayfield Fellows program brings together entrepreneurial Stanford students for an intensive summer working at early stage startups in SF.
That sentence contains the entire housing brief, if you read it carefully. Together. Intensive. Summer. In SF.
Why this is a genuinely hard booking
Program directors reading this will recognise every one of these constraints. Everyone else tends to underestimate the problem.
- The dates are fixed and non-negotiable. The internship starts when it starts. There is no flexing by three weeks to find a better rate.
- It is a dozen people who must be together. The cohort is the pedagogy. Scatter twelve fellows across six sublets in six neighbourhoods and the program has paid San Francisco prices for the one thing it specifically did not want.
- They are students, not funded founders. Interns on intern pay, often without US rental history, credit files or prior US landlord references — which is exactly what a conventional San Francisco lease demands.
- The internships are all over the city. Different companies, different offices, so the house has to be somewhere that works for a dozen different commutes.
- It is roughly three months. Too long for a hotel, far too short for the twelve-month lease landlords prefer — in a market where median two-bedroom rents passed $6,000 in 2026, active listings fell about 30% year over year, and vacancy in the neighbourhoods anyone wants sits near 3%.
- Nobody has time to furnish anything. The fellows arrive, start work, and leave twelve weeks later.
Put bluntly: the standard rental market has no product for this, and the people who need it have the least leverage to get one.
Summer one: Pacific Heights
The first cohort took a house in Pacific Heights.
What we were optimising for was not luxury. It was the ability for twelve people with twelve different jobs to live one life: enough bedrooms that nobody is sharing who does not want to, common space big enough that the default evening is everyone around one table, a kitchen that survives a dozen people, internet that holds, and cleaning that happens without a rota taped to the fridge. One monthly price covering rent, utilities, internet and cleaning. One person to call when something breaks.
Two fellows described the result in testimonials on our site. Divya Ganesan:
Our Mayfield cohort needed a home in SF where we could live together, focus on our internships, and actually feel like a team. The Pac Heights location was perfect, the house had everything we needed, and Pedro made sure we were taken care of. It became more than just a place to stay... it was the home base for one of the best summers of our Stanford experience.
And Ariane Lee:
Staying at hyperstay during our Mayfield fellowship was the best housing decision we made. Living with the cohort in Pac Heights meant we could walk to our internships, explore the city together, and come home to a space that actually felt like ours. Pedro genuinely cares about his guests and it shows.
Two details in those quotes are worth pulling out, because they are what we actually design for and they are easy to miss.
"Actually feel like a team." The cohort arrives as twelve individually selected students who barely know each other, and the program needs them to finish as a group that teaches each other in the autumn. The house does a large share of that work, for free, simply by making the default evening a shared one.
"A space that actually felt like ours." This is the difference between a house and an aparthotel. A cohort that has the whole place behaves differently from one distributed across a building of strangers: they cook, they argue about what they are building, they bring colleagues back. That is the product.
Summer two: the whole building in Russian Hill
The following year, the program came back — and this is where the second booking tells you more than any testimonial could.
Andreas Lorgen, who organised it, wrote:
We chose hyperstay as our home base after our last cohort had an amazing stay and how well it matched the needs of all of us!
For summer 2026 the cohort did not take a house. They took the entire Bernard Street building in Russian Hill — all three floors, ten private bedrooms, for 90 nights, from 15 June to 13 September.
That configuration is unusual and it is worth explaining why it works so well for a program. Three self-contained floors in one building gives you something a single house cannot: the cohort is unambiguously together — same front door, same building, no commute between fellows — while each floor still functions as its own flat with its own kitchen and living room. Twelve people who want one big dinner can have it. Three people who want a quiet Tuesday can have that too, without anybody negotiating.
Russian Hill also solves the twelve-different-commutes problem about as well as San Francisco allows: central, residential, walkable, and well connected to where early-stage companies actually sit.
The booking was direct, one block, one arrival date, one monthly price per resident covering rent, utilities, internet and cleaning. No deposits chased across twelve students, no twelve-month lease, no furniture, no utility accounts, no internet installation waiting three weeks into a twelve-week internship.
What the fellows go on to do
This is where we want to be careful, because it would be easy — and dishonest — to take credit for other people's careers.
The Mayfield Fellows are selected from Stanford at a rate of twelve a year and mentored by venture investors and alumni; they were going to be impressive with or without a good kitchen. What a house can do is remove the friction around an intense twelve weeks, and let the cohort effect happen. What the fellows do with that is theirs.
One example we can point to, because he is on our homepage: Shaurya Sinha, a Stanford Mayfield Fellow, is building Sherpa Labs — bringing AI tutoring into public school classrooms, with the aim of personalising education for every student rather than only those who can afford it.
If you are a Mayfield alum who stayed with us and want your company listed here, write to us — we would rather publish what you tell us than guess.
What we would tell another program director
The transferable lessons from two summers, in order of how much they matter:
- Book the whole building, not rooms in several. Everything the program wants from co-location depends on one front door. This is the single highest-leverage decision.
- Lead time is the real currency. With vacancy near 3% in the neighbourhoods that work, a block of ten to twenty rooms is a quarter-ahead decision, not a three-weeks-out one. Programs that tell us their dates early get the house they want.
- Specify common space, not bed count. Ten beds with a small kitchen and no shared table is a worse cohort house than eight beds with a big one. Ask how many people can cook and sit at once.
- Check bathrooms against beds. The most common complaint in badly specified group housing, and the easiest to avoid.
- Make the price one number. Students cannot chase a utilities split twelve ways. Rent, utilities, internet and cleaning in one monthly figure removes an entire category of administration from the program.
- Qualification matters more than you think. If booking requires US credit history, a chunk of any international cohort simply cannot take the room. Ask before you commit.
Booking a cohort
hyperstay runs furnished homes across San Francisco — Pacific Heights, Russian Hill, Nob Hill, the Richmond and North Beach — for founders, fellowships and corporate teams. Private rooms or an entire house with six or more bedrooms, 30-night minimum, with rent, utilities, internet and cleaning in one monthly price, and 21+ rooms available across the portfolio when a program brings a group to the city together. Alongside the Mayfield Fellows we have hosted founders and operators from Y Combinator, Hexa, Latitud and General Catalyst-backed companies.
If you run a fellowship, an accelerator cohort, a research program or a corporate team coming to San Francisco, send your dates and headcount to team@hyperstay.com and we will come back with what fits.
And if you want the honest version of a reference, ask us for the second booking. It is the only part of the record that cannot be written by a marketing team.
