I absolutely loved staying at Carter & Kaleen's apartment! It's within walking distance from the 24th Street BART station, but be warned that it's more than a 10 minute walk and some of it can be pretty steep. I do not recommend walking if you have heavy suitcases.
The apartment itself is spacious, very well designed and comes with an amazing view of the city. They're currently building an outdoor deck for the apartment which I have no doubt will be as amazing as the apartment is itself. The welcome basket that was left for me was filled with not just wine, but a wonderful array of snacks & healthy eats. I really appreciated the bunch of bananas! :)
I felt right at home the second I walked in. Comfortable couches, very comfortable bed, and a well appointed kitchen.
Kaleen and Carter were the nicest hosts. They gave me a tour of the space and were very responsive and attentive. I loved their idea of a chalkboard with guest's recommendations on it as well as their own. This served me well with Goat Hill Pizza. There a TON of great restaurants within a short walking distance from the apartment.
I definitely recommend staying here if you're looking for a more relaxed SF experience.
