Staying at Peter's place was great - fantastic location, was pretty much walkable (or bikeable - bike rental places everywhere!) to anywhere you might want to go in San Fran. Right next to Lombard St!
Peter was unfortunately not in town for our stay but his friend Paula met us to hand over the keys and explain the place. Both Peter and Paula were extremely helpful and very gracious when we had to contact them very late on a Sunday night after jamming the door lock.
Would absolutely recommend this place to anyone - great hosts and a great spot. Thanks so much!
