We stayed for 3 nights at Jeff's studio. We had a great time, the studio is spacious and well decorated a stylish way. Everything was super clean and Jeff provided some nice touches like coffee and chocolate bars. Bernal Heights where the studio is located is safe and a beautiful neighbouroud. All in a great stay and recommended when in SF. Just be mindful it's on top of a rather steep hill and a 20 minutes walk to the subway.
