We really enjoyed staying in Peter's apartment. It had a perfect location for walking (we did a lot of walking up and down the hills of SF!) around San Fran. Peter had very kindly got hold of a cot for our daughter plus we got an extra chair for her for the kitchen. Our daughter enjoyed Peter's dog and even though the flat wasn't child proof we didn't have any real problems.
We also used one of Peter's recommendations for a Chinese restaurant and he was right. It was a great place.
