Overall we really enjoyed our stay! There was straightforward booking process and checking into the property was very easy. The hosts were very responsive, as well. Although it's not located in an area that people may normally book for a trip to San Diego, we didn't have any issues walking the surrounding area for a bite to eat or finding cheap transportation to other areas. The upstairs room can get quite hot in the middle of summer (although we didn't have an issue in July), but it appears as though the property owners are aware of this and are planning to install A/C. We comfortably fit 4 people into the Airbnb on 2 beds and an air mattress, and the couch is also very comfy and could've been used to fit one more.
I'd happily recommend this booking for anyone traveling to San Diego!
