CoLiVilla was a great place to stay for the month I was in San Diego for work. Golden Hill is right next to Balboa Park, you can drive 15 minutes to OB or 20 minutes to La Jolla. Airport is a 10 minute drive. Golden hill is a safe residential neighborhood with some good neighborhood restaurants and bars. I could walk 30 minutes to the Gaslamp Quarter or South Park.
The Airbnb is exactly how the pictures and descriptions depict it. Kind of an adult professional hostel vibe. If you are social there are always new housemates to meet. We even all planned a BBQ one day in the backyard. The house keepers that come daily keep the kitchen and common areas clean and make fresh coffee. There is also free laundry in the house. WiFi was good. Parking was free street parking, which was never an issue for me. Definitely a place I recommend for short trips or even longer business trips.
