Review Score: 6

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.
