The building had very little insulation. We were unable to sleep, could hear everything in the neighborhood around; car doors, bicycles, every car that would pass, the other neighbors, drunks in the alley, airplanes, it sounded like people were coming into the house and very scary at night. And the airplanes were worst then anywhere we have stayed in San Diego before. We stayed less then 12 hours as we arrived late (due to our flight) and vacated as soon as possible the next morning at 6:30 am (having not slept the 6 or so hours we were there and then around 6:30am the planes overhead start flying like they are about to take the roof off), having to find a last minute arrangement for a place to stay. The listing mentioned slight noise of the airplanes, however this was extreme noise, as we have stayed in San Diego for over 3 years and are aware of the Airplane traffic, this was unacceptable for having a vacation where we wanted to sleep in and enjoy our rest. I suggest they put some sort of noise canceling machine in the unit and/or explain really how loud the place is! I asked to make a deal to receive a refund for the nights/days we were unable to stay or at least part of the amount as we were unable to stay and the host declined without exception. We stayed there less the 12 hours, tried to sleep and used nothing else in the entire house nor used it for the length of stay we had planned and the host offered no refund or was not willing to return any of our money. Bummer it didn't work out. Was so excited and had a horrible experience.
