Average but worth the price!
I stayed there over the Easter weekend with my daugther and we had only good experiences. Close to a lot of SF attractions, e.g. Chinatown, Market Street etc.
Service is professional, not overly engaged or friendly, but we had no issues with anyone. The flair of the hotel is quite continental, a bit strange in decoration, but for a hotel of this age approriate and one can find it charming, too.
Only two things to be aware of - hotel windows are single pane, thus a bit noisy in the morning (at least for rooms towards the front with the street) and of course parking a car in the center of SF, well costs a fortune (minimum $25 a night), as parking spots at the curbside are extremely rare to find....
