This is an excellent place to stay in San Francisco! The room is bright and clean and has a large comfortable bed. The private bathroom is right next door. Both the bedroom and the common area have beautiful views over the bay.
Sarah and Mark were friendly and very welcoming (as was their adorable dog Clover). They respected our privacy but responded instantly whenever we had any questions.
The location is good. It's a quiet residential area but other parts of the city are easily accessible. For trips outside the city, the 22nd street station caltrain station is less than 10 minutes away.
We will certainly try to stay here if we come back to San Francisco.
