My wife and I have stayed with airbnb numerous times. We always had an excellent experiences (100%). We convinced her parents to try it in San Francisco. We were extremely regretful of that decision.

There were other airbnb renters staying above us over the extended weekend. We were there to see the sights as regular tourists. The people above us were there to party. Beginning at midnight we were awakened every night by the party above us. Night 1 ended at 5am, Night 2 at 3am, Night 3 at 3am. Night 4, we were finally able to get normal rest. Loud music, banging around, jumping on the floor, slamming the front door that was right outside the window by the bed, yelling in the front yard - again right next to the window. After we asked them to quiet down the noise continued, so we contacted the owner - still the noise did not stop.

The quirky things that were wrong with the place would have been fine, if we could have slept through the night. No plug ins, spotty internet, no disposal, can't use microwave and toaster simultaneously, is fine if you can sleep.

We weren't prepared for the hostel/college style partying above us in during our stay. We hope to never experience it again, it was a nightmare and ruined our vacation from the east coast that we spent tons of money on
