The apartment was exactly as described and then some. The neighborhood is situated very close to the beach, and it is quiet and safe. Inside, the apartment was spacious, bright, and extremely cozy. We had five people in our group and we all felt like we were at home.
At one point, I notified Felix of some broken slats on one of the beds purely as a heads-up, as it didn't affect our stay and that part of the bed wasn't being used. When we returned after a long day, we discovered that the owners already came by to fix the bed, which was not necessary, but it really showed how much the owners cared that we had a good stay.
I will definitely stay here again the next time I visit SF again. Thanks again, Felix and company!
