Jennifer was very helpful and I would recommend this place for sure. She helped us get free tickets to the MOMA too which was nice. Staying at Jennifer's place was great for the ~10 days we were there. It's very central to the Mission and close to lots of great places to eat and drink. The price for our stay was a little high, and aside from the (small and limited) kitchenette it's not much different to paying the same/less for a hotel room.
The hot tub was a great touch though and very cozy -- well situation in the garden with some nice smelling trees and flowers around.
The apartment is a little darker than let on by the pictures, especially when SF isn't sunny 100% of the time. That said, it was perfectly adequate. Not sure I would stay here for a long trip, but a week was OK.
