We definitely enjoyed our stay at Jan's place. We (3 guys from Germany/Luxembourg) have been living there for about 1.5 months, and the money was really worth the stay. The view of San Francisco is amazing, the flat was clean when we moved in, and the neighbors were friendly. Jan was a caring and reliable and friendly host, who was always available when we needed him. Overall our stay was excellent and deserves 5 stars! If we ever go back to SF, we will definitely come back if possible!
