Jeff, the owner, puts in a lot of little touches like chocolates, wine, and restaurant suggestions. The touches are nice, but more importantly, they signal that the owner is attentive, and that's exactly what we got with Jeff: prompt and friendly responses to our enquiries, easy check-in/out, and a spotless unit with everything in working order.
The unit itself is a standard apartment and the neighborhood doesn't look like much. However, it was safe, with a decent (but not loud) nightlife and restaurants just a block away--lots of well-dressed people going to the brewpub or the Madison on the weekend. (If you stay here, do not miss eating at the Madison!) All the stores within walking distance were friendly and chill (Twigg's coffee, Liquor/convenience, artisanal ice cream, a pie shop, Sprouts market). The area looked like the kind of place that artists are moving into as they get priced out of more expensive areas. University Heights was convenient for us to travel to other areas (20 mins to La Jolla, 15 to Mission Beach or Sea World, 5 mins to the Zoo/Balboa Park, 5 mins to a big shopping complex).
We had a great visit, and we'd stay at this or another of Jeff's units anytime we came back to the area.
