We had a wonderful stay at Ken's and Richard's! Great location, quiet and cosy apartment and wonderful attentive and professional hosts, topped with a parking spot for a small car (a big plus when you come to SF w/ a car).
The apartment is located at the back of their house facing a quiet garden, complete with a small porch for breakfast. It is right in the heart of southern Mission, with tons of great food options nearby (also very close to public transport).
Ken and Richard's food/restaurant recommendations were excellent!
We would always stay with them again!
