This apartment is great! It's at an excellent location, right between the best spots in The Mission and in Hayes Valley, and quite close to the Muni/BART. The apartment was clean and pleasant -- it's a beautiful place with very high ceilings, which was really fun to stay at. The host was very responsive and helpful whenever we needed anything throughout our 3.5 month stay.
The only downside in the apartment is that there's some street noise, as expected from staying at a street level apartment in that area. However, the bedroom is far from the street, behind two doors, so it didn't influence our sleep. The area felt quite safe though, in general.
We highly recommend this place!
