My husband and I really enjoyed our stay. Justine is very responsive and informative. The BnB was exactly as expected from the description and location. It's true that you can hear them upstairs so if that might bother you, just bring ear plugs or sleep with headphones.
The West Portal neighborhood is very clean and safe, and has a cute little avenue by the Muni station. We went to the wine bar and the ice cream parlor twice. The BnB is just around the corner from the station - you really can't get better than that. The ave was great to unwind after coming back from a long day in the city.
We also loved the 8-minute drive to Golden Gate Park! San Francisco is just amazing.
