Probably the best bang for your buck!
Nearly everything is new from bed to t.v. to the wine glasses and everything in between. It has some of the best food spots within walking distance and downtown is about a $5-10 uber ride (a couple miles). Basically as center to San Diego as you can get while staying out of the downtown hassle/price. Check out the map in the photos.
The house is small, so four adults are doable but it will be cozy. Also, the bathroom access is through the bedroom.
