I have stayed at Aaron's house a few times now and plan on continuing to stay here each time I visit San Diego. My trips are a combo - work and personal and the space is great for relaxing in and also has great wifi and plenty of table space to work.
The backyard is really nice with a fountain, and fruit trees and a picnic table - I often work out there and eat out on the picnic table since the weather in San Diego is usually so gorgeous :)
Ultimately, though, the main reason I stay at Aaron's is the bed. It's more comfortable than my own bed at home. I sleep awesome here every time and I find that beds can be hit or miss at so many AirBnBs, so finding a great bed at Aaron's has been so wonderful. There are two bedrooms and both have the same awesome bed comfort, as well, btw.
The kitchen is really nice, too, and it's a great space to cook in if you like to prepare meals on your stay.
Neighborhood is highly walkable. I walk to get my groceries and there are nearby bars and cute restaurants.
