Summary: Excellent friendly service. The rooms are roomy and the hotel is elegant. 5min walk from Union Square. Parking is outrageously expensive. Plenty of transportation options. Why not a perfect score? Parking is very limited and used for 2 hotels. Sometimes drove in the tight space that the garage is over and over until we found a spot. Maintenance is mediocre; the bathtub was clogged and should have been noticed. The back of the hotel, where the parking garage is, is very sketchy. Lots of homeless and some doing drugs. One of them yelled at my husband for no apparent reason. Oce we realized this we never walked that street again. I will stay here again, this was my 4th stay. Cable cars a 3-4min walk away.

Summary: The room was nice, but two ladies at the front desk/concierge were incredibly rude. Not helpful at all. Felt like they just wanted people out. Will never stay here again.

Summary: Lighting in the room is dim. Shower water pressure could be much better. Hallway noise came through the door. Ok for $220 a night. I tried calling housekeeping, but no answer. No one answered when I called the hotel directly.

Summary: The buffet breakfast had lots of choices and the food was reasonably good. Bed was comfortable. Union square location was near powell station so we had convenient access to the free muni during the weekend.

Summary: It is so annoying to be forced to buy $70 of food and, in addition, have a “resort tax” of another $80 on top the the hotel fee. It wasn’t transparent.
