We had a lovely stay at the Marina Hotel. It's a very pretty little setup with a courtyard filled with flowers and tons of privacy from Lombard Street for the interior apartments. We stayed in one of the corner units and didn't hear much at all from the streets. Quietest stay I've had in San Francisco ever. Plus the lovely breeze flowing through made for excellent sleep. The rooms aren't anything fancy or over the top but the location is excellent for a walk to food, the marina area, and the palace of fine arts. Bring a few lawn chairs and people watch all day long. If you aren't expecting super fancy, like a great location near food, bars and convenience - this place is for you!
