Great place to stay. Beautiful little apartment in a very nice part of San Francisco, 2 minutes walk to the Muni station into the middle of town (15 minutes to Embarcadero in one direction and Golden Gate Park in the other).
We were staying with our three year old daughter who loved the outside bath and the fact that there is a playground in the park right next door.
Susan is a great host, very welcoming and full of useful hints and tips.
Perfect base for SF and if we're ever back we would definitely stay here again.
