Rooms are clean and tidy, and I was expecting a little more amenities, but given the price and location, it's pretty reasonable.
Super friendly and helpful staff, and they helped me switch rooms when my balcony room got too noisy at night (not much sound proofing there). They did provide ear plugs though.
If you are a light sleeper, you'll probably want ear plugs anyway as I could hear the guests talking in the neighboring rooms (or maybe they were just speaking loudly) after switching rooms (previous room was on the corner).
But I'm nit-picking here. Location is great, it's in a good part of town and close to all the good stuff - Fort Mason, Polk / Union / Chestnut / Fillmore Street, curvy part of Lombard Street, Fisherman's Wharf and Pier 39, Japantown...etc. And there are many cafes or diners close by as well. Almost everything (to me anyway) is within walking distance.
All in all, I had a good stay and would come back again.
