My family and me had a great time at John's house. The place was spotless clean, with a great view and exceeded our expectations in every way. It's not the cheapest option, but you get what you pay for, and this place enhanced our overall experience.
For the few times I exchanged messages with John, the replies were polite, kind, and fast. There were no issues to report, just a great time.
Overall an awesome experience and would recommend to friends and family going to San Francisco.
