Michelle and Peter are great hosts. The apartment is in a great area and very convenient for pretty much any activity in San Diego. We really wanted a place that was decently private and allowed us to park a car. There are grocery stores, gas stations and cafes nearby -- a great spot to use as your HQ as you hang out in SD.
Some others have noted that it is particularly noisy here. While I would not describe it as being a silent night in the country, I feel like most parts of San Diego are similar to this. The apartment is adjacent to an alley, and there are occasionally vehicles coming and going. We didn't really find this to be an issue for us.
For parking, we parked on the street in front of the main house (Island Ave). We would leave in the morning for most of the day and return in the evening. We never had any difficulty finding a spot within the block.
For morning coffee, we highly recommend Dark Horse Coffee roasters (very close to this Airbnb), and James Coffee Co. in Little Italy (India St, 5-10 minute drive).
