Well, it is a shed, but it's really not bad if you're on a budget. You'd be hard pressed to find a less expensive place in the area. The location is very central to much of San Diego and made my commute to work very easy. The heater works which was very fortunate for my stay.
The host is very friendly but seemed to have a lot going on. The room wasn't quite ready when I arrived but was enough to get in and get some sleep. Then I never got a response for my request to extend my stay. Taking the time to write more thorough check-in notes would be useful as well.
Another thing to note was parking on premises was listed, however, the gated carport appeared to be used for storing the trash cans and other items. Perhaps I could have asked about parking inside but my lowered car would not have been able to pull in.
