I booked this place because it was billed as a "quiet retreat", but I found it anything but. You should know that you're going to be *right* next to Noe Valley's main drag, which means you'll hear constant bidirectional street traffic (especially if you crack open a window). What's more, because of the building construction, you may hear conversation and music from next-door neighbors in the evening and night hours, as I did.
After two restless nights, I ended up canceling the reservation, in keeping with the host's long-term cancelation policy, and moving into a hotel room. When I sent her a polite notice letting her know, she ignored it for two days, and then sent me a note with a personal attack ("you must have noise sensitivity").
