The lobby is nice. The room i was booked into was beat up. The bathroom was actually very nice. The room itself left a lot to be desired. - chipped paint, bland wallpaper, mismatched furnitures. But the bedding was good. So you can see the mismatch above. It would be really easy to make the room more desirable. But in its current state, I won't rebook.

Old hotel but completely remodel. Carpet and beds extremely clean, walls panted and modern shower and bathroom. Very convenient location, close to all main downtown attractions, cable car and bus stops. Area seemed safe enough (it’s still downtown SF). I’m 4 stars because the rooms and bathrooms are really really small. The bathroom sink was in the room itself, to say how small was the bathroom. It was not a problem for us as we were out most of the day, but if you have 2+ people with different habits, get ready to have not much personal space and privacy. Overall a good experience!

It was just OK. But it was balanced with what we payed. Don’t understand the “resort fee” in this hotel, it is obvious in Resorts but not in this type of properties.
