My girlfriend and I stayed two days at Peter's appartment, which is a real nice place for visiting San Francisco!
The appartment itself is great and well laid out, and a lot of San Francisco attractions are within a walking distance (for the others, MUNI transportations and bike rentals are also around the corner). And last but not least, the location is surrounded by a lot of restaurants (Peter kindly provides a guide with his personal preferences) !
About Peter, unfortunately due to personal obligations we haven't seen him a lot, but the little time we spend with him was really enjoyable. It was also great to meet his friend Paula, who welcomed us while Peter was away.
We will definitely recommend Peter and his appartment :)
