Rich's AirBnb is an excellent place to spend a few days in San Diego! My wife and I were very impressed with it!
When we had difficulties checking in (being able to get the electronic front door to lock when we wanted to leave), he was very responsive and provided a way for us to do so. Although, we believe it should be made known in the description of the place that it is necessary to download an App in order to lock the front door, which we were not able to get to work, to do so. But he provided another way to lock/open the door, so It all worked out.
So we were very happy with the AirBnb and we would highly recommend it! A+++
