Awesome hotel, great location!
It was our 10 yr anniversary and I had mentioned it was in our reservation. Via Tripadvisor got 10% off. It was great from the very beginning! They even were prepared and greeted us by name.
The hotel was not huge, but it was enough for where you would normally need to go in SF. Lobby was nice, had some refresher drinks ready every day so when you came back from your long walk or journey you could just get some cups and get something there on that table. Nice touch.
Rooms were really nice.. great views. We got the cheapest King size room facing the street, but it was totally fine. You won't miss anything if you look for the lower priced rooms.
Hotel also gave us some chocolates to just say happy 10 year. Unexpected. 
The location I have to say was really great. It was in the middle of everything (drugstore, shopping, taxi's etc) so you don't have to worry about being in the middle of nowhere or far from where you want to be.
Tip: certain more expensive taxi's have some agreement with the hotel. If you want a cheaper taxi, just walk out of the hotel and then flag a taxi down. Those hotel taxis are nice for a date or something but if you just need to get to Chinatown or something you can save $10 or so.
I hear it's great with children but we went as a couple this time :)
