The is a great location for sightseeing in SF! Nob Hill is located near everything- and the trolley stop is right outside! The space is clean and new and the facilities were quiet inside. There is some street sounds, but it's the 4th floor and not too bad. There's no elevator- so plan accordingly with luggage size and stair taking ability. Communicating with the host was great- the turn around time for responses was only a few hours. Great spot all around- highly recommended.
