We were only at Peter's for a short time, but enjoyed meeting both Peter and Haley. For the price and location, this place is definitely a must. Convenient to walk to Chinatown, Fishermans Wharf, Pier 39, Lombard Street and easy access to transport links too (although we didnt find we needed it).
Peter is kind enough to provide a folder full of information and tips on things to do and eat in San Fran, he even started a book for guests to write their own tips in! We were lucky enough to be the first to write there.
The bathroom was very small for what we are used to, however thats probably what you'll find in most houses in San Fran. We managed fine and still had a good nights rest in the comfortable bed!
