This is a great place to stay if you're looking for a reasonably priced room in a convenient city location. The rooms are bare bones, but comfortable and clean, and the common areas offer a small kitchen and free coffee. Having a small fridge in the room is a nice touch! Consider bringing a power cord if you have several items to plug in; the outlets in my room were behind furniture and/or already full.
Very convenient to the Montgomery BART and all Union Square shops and restaurants. Polite and helpful front desk service. Feels safe, and would be a good home base for a longer term stay.
