Culture and history mixed with new-age tech. Stay in the heart of San Francisco at FOUND Union Square. This recently remodeled building starts with a mid-century modern black and gray brick exterior. The refurbished lobby is coated with subway tile accent walls and herringbone-style floors. Earth tones and wood finishes add a simple yet modern touch to your space. The shopping district is just outside your door. You could easily spend a day at Westfield San Francisco Centre — a nine-story mall with over 170 retail and food options. Take a stroll to The Painted Ladies or indulge in fresh seafood at Fisherman's Wharf. Treasure this high-spirited city at FOUND Union Square. This is a central location and prone to city noise. There's no cable, daily cleanings, or luggage storage. We've partnered with Vertoe in multiple locations around San Fransisco for you to drop your bags.

Tripadvisor’s approach to reviews
Before posting, each Tripadvisor review goes through an automated tracking system, which collects information, answering the following questions: how, what, where and when. If the system detects something that potentially contradicts our community guidelines, the review is not published.
When the system detects a problem, a review may be automatically rejected, sent to the reviewer for validation, or manually reviewed by our team of content specialists, who work 24/7 to maintain the quality of the reviews on our site.
Our team checks each review posted on the site disputed by our community as not meeting our community guidelines.
Learn more about our review moderation.

The stay was GREAT. I loved the aesthetic, the bed was cozy, and there was a huge shower. I would absolutely stay here again. The electricity situation is a little wonky, and it went out on us twice, but the front desk was able to fix it within minutes.

Kudos to Gideon for his extremely helpful and personable assistance, such a star! Also H and Sarah, brilliant staff. Good central location at a reasonable rate. We had a small but perfectly functional room - if you’re spending too much time in your room your not seeing enough of the San Fran sites!

Slightly expensive for what we got - we had a bunk bed room with a small window so it was a bit too dark. Also the AC had broken in the whole building so it was constantly boiling. But the hotel provided us with a large fan so this helped. Also the beds were super comfy. Decor in the room and reception was nice, and I cannot recommend the location more. Perfectly central for all public transport. Some reviews said lots of homeless - this is an issue everywhere in the city, just be careful and try not to go anywhere dark alone (stick to main roads). The hotel has a receptionist most of the time (not 24 hours) and they were helpful, they gave us lots of tips for the tourist things we wanted to do. It’s also good that the doors have codes instead of keys as you don’t have to remember your key. Laundry was $1.50 per wash and per dry. The hotel has a communal lounge which was a nice touch. I would stay there again purely because it was pretty and had a good location.

I needed a last-minute, affordable hotel in downtown SF and was anticipating the possibility that the accommodations might match the low price after reading some reviews. I was pleasantly surprised. Beds clean & comfortable, air conditioning worked well, hotel staff pleasant & helpful, comfortable lounge and workstation, nice shower amenities. We did have fire alarms go off around 4:30 am and had to evacuate and while I did not see a staff member, the SFFD was helpful and reassuring, and all of us guests had the bonding of standing outside in the dark in our pj's for a little while. I'll definitely start with Sonder at FOUND if I need to return.

As a frequent traveller, I am suprised by their low service level. My impression is that Sonder does not value the customer. For me Sonder is the Ryanair of the hotel industry. It is cheap and there the benifits end. I will not book again.

We booked a 4 bed up & down bunkbeds. Very cute & functional room. Value for money room price for the area. The bed was comfortable w/ a lot of sockets/ charging area. Staff was very friendly & helpful with all our questions & inquiries. Appreciated the early check in & late check out request thaf was granted thru the app ( download the Sonder app for updates about your stay). We appreciated the free chocolates upon check in & the free coffee/tea/water located on the 2nd floor. We felt safe inside the hotel and will definitely stay here again.

We really enjoyed our stay. The hotel was very clean. Staff was helpful and friendly. I will definately use Sonder again. Not sure why app is forcing me to write 200 characters but whatever. The place was very good. Close to good restaurants. Bedaga was next door. Mason Cafe one block. Also a very good Italian just three blocks
