This unit was perfect for our stay in San Diego, focused on visiting the SD Zoo and Balboa Park. Our 7 year old was very happy in his own room, and we found our room comfortable and light, with direct access to the deck overlooking the canyon. I would have preferred cotton sheets (they were microfiber), but that's a personal quirk and not at all a deal-breaker. The building seems to be vintage 1950's or so, with a cheerful IKEA-style interior remodel to update it for modern tastes. The kitchen is functional with a reasonable variety of supplies. The bathroom is small but usable, with a nice shower-over-tub. We did not use the television (a large modern flat screen with a speaker bar), so I don't know how that is.
We could hear the upstairs/adjacent neighbors a little bit, but with the host's very clear quiet hours and no parties policies it was not a problem at all (we've heard much worse in nice hotels). The neighborhood felt very safe and quiet. The host was very quick to respond to communication when we had a request. Check-in was extremely easy with the coded front door lock. All-in-all I would definitely recommend this unit for a convenient and comfortable stay in San Diego, walking distance to Balboa Park and the San Diego Zoo, and not far from many wonderful restaurants.
