Do not book a room...

Liked: Front desk staff were friendly.
Disliked: No air conditioning. No amenities. No ice bucket or glasses, no coffee maker, no drawers for clothes. Extremely small room. No lobby to speak of. One very small, rickety elevator. We booked the room with a non-refundable rate long ago, but I never expected a hotel without air conditioning. Had I known that , I would not have booked the room. Management would not consider even a partial refund, so we're stuck.

Okay

Very good

Superb

Liked: Good location, however an ear plug is recommended since Market street facing rooms are loud due to traffic. Staff is helpful and flexible if you have extra needs. Atmosphere and design of the hotel is is unique, rooms and floors are clean. 0- 24 hours lobby service.
Disliked: Pay attention, queen size beds are only 180 - 185cm long, not 2 meters as expected based on international standards. In certain rooms you have to wait couple of minutes until you get warm water, but this is not deteriorating your comfort at all.

Passable

Disliked: Room is too small, area is a little ghetto

Pleasant

Liked: The hotel was fine, rooms were clean and comfortable
Disliked: My room faced the street so it was very noisy! Also, the room had morning sun which made the room heat up like a sauna as soon as the sun was up. No cooling system or even a fan. Made it quite uncomfortable to be able to sleep in and get ready for the day.

Small but friendly, centrally located...

Liked: On the plus side, the hotel staff was all extremely friendly and helpful. The hotel is a good value for San Francisco, located in an area that is pretty safe and walkable, and close to the trolley stops. Overall, it was a decent place to stay, and there are rooms available that are larger if you are willing to pay more.
Disliked: Very small room, and hotel has no lobby or reception area. You enter, check in through a window, and it's up the stairs you go to your room. So if you need to do some work or hang out for a bit outside of your room, there's no place to do that. The room was clean, but the bathroom smelled like mildew, probably from the bath mat. Several cracked tiles in the bathroom.

Passable

Cozy hotel in Market street

Liked: Updated hotel was cozy and nice. Wifi worked quite wel. I liked a coffe and tea at reception - really good to compare to regular american coffee in other hotels. Definetely i would stay again.
Disliked: We had a problem with water (no hot water) in one room. Then we got other room and it was better, but last morning the shower was not working at all. It seems the hotel is in old building and that makes additional issues to maintanance water suply.
