Unit is exactly as pictured (always a good thing). Clean, bright, and comfortable. It was also well supplied probably one of the best I've stayed at, unlike some places where you get half a roll of toilet paper and 1 towel for a week.
Host is very responsive. Only issue I had was with parking at midnight one night, when a neighbor boxed me in, which was not the host's fault. Even then she was responsive. Check in and check out were easy.
I'm a light sleeper. I did not have any issues with Belmont Park perhaps because it closes so early in the winter and is only open on the weekends. I did get woken up by planes my first night pre-dawn but then I got used to it. The last night pre-dawn I got woken up by the garbage men. Outside of that it was quiet and I got good sleep.
I would stay here again. I loved San Diego, there's so much to do I didn't get a chance to see everything. Have fun!
