We stayed here twice at separate times over a long weekend in lovely San Franciso, so I'll repeat my praise from the other booking! Also, the staff at the front desk was happy to hold our luggage, which was super convenient for getting in a few last activities before heading to the airport or elsewhere.

Great little place right in the most desirable part of town! Literally across the street from 5-star hotels, one block from the Muni and BART, and a few meters from the cable cars, staying here puts you in the middle of everywhere you want to be in San Francisco. You can BART directly from SFO airport to Powell Street station.
Friendly front desk staff and safe feeling entrance from the street. We got checked in quickly and there was always a friendly face at the counter. A lively bar and coffee shop downstairs are great for drinks/snacks/coffee. The entrance is inconspicuous but that actually makes it feel very private and exclusive.
Room is small but comfortable, with a great bed and cozy European style comforter. Has a sink in the room with toilet and shower directly adjacent - the "shared bath" was a non-issue. Window opens up onto backside of building, so there's no street noise. Closet, small table - basically all you need.
We loved staying here and would definitely recommend it to a friend and will certainly stay again next time we're in SF.
