We had a good stay in San Diego and enjoyed the location and the spaciousness of Anthony's apartment along with its kitchen and dining area. Everything else with the apartment was "just good enough". It is very noticeable that this is a place meant to be let as there are lots and lots of small details that could easily be improved and overall add up to making the place feel fairly worn down.
For example, sockets were loose, blinds were loose or left lying on the floor, ribs for the bed were sticking out from under the bed, the wifi was spotty, and there was loads of hair left from a previous guest on the rug in the main room. When we mentioned the last point to Anthony he promised to get a vacuum for the next day but never did. (He was very responsive throughout and helped us with codes a couple of times though.)
In terms of the location it was great to be close to everything in Little Italy and the waterfront but it came with the downside of the neighborhood being fairly lively. It is also located very close to a train crossing and the bells are noticeable through the night. As there are almost no blinds the apartment gets bright as the sun rises, so make sure you'd be fine with that.
