I stayed at the studio for over a week earlier this month. It's very cutely and prettily done up, exactly as shown in the pictures. It's a comfortable space, with easily enough room for 2. It's located a fair way up a hill (like a lot of San Francisco) so we had to take cabs to commute mostly. There is a MUNI stop 10 minutes walk away but it's downhill only on the way out. It depends on when you're spending your time but - Castro, Noe Valley etc. are quite nearby. The nighbourhood is lovely!
Like Amanda's mentioned already, the ceiling is quite low. So you can hear people walking around over your head which is slightly disconcerting.
Besides that the space is definitely beautifully done up and well equipped. Amanda was very communicative and kind enough to hold our suitcases until our late evening flight.
Minus the location (which only matters since it's a few miles away from work), I would definitely stay here the next time I'm in San Francisco.
