My friend and I thoroughly enjoyed our stay here. It exceeded my expectations in nearly every respect. The hotel is in a great location (i.e. close to many great restaurants, stores, BART station, cable cars). We were in town to attend some baseball games at AT&T ballpark and we could easily walk there from the hotel.
The staff was very professional and extremely polite. We had interactions with the front desk, maid service and concierges and they all did whatever they could to make sure our stay was an enjoyable one. The concierges really spent a lot of time with us pointing out the best ways to see the sites and for that, I'm very grateful.
The room was really terrific (we had a double Queen). It faced Powell Street so it was a little noisy at night, but it's a major city so I wasn't put off by it. The size of the room was bigger than expected. Plenty of room to spread out and store all of our clothes, plus the safe and closet came in very handy. The bathroom was very clean and the tub had one of the best shower heads I've ever used.
The room had an air-conditioner but we never turned it on the entire week we were there. The room stayed nice and cool so long as we kept the windows cracked open.
For someone on a budget, I would highly recommend this hotel. It's location is fantastic and the staff made us feel right at home. I would definitely stay here again the next time I visit San Francisco.
