The guest house was a great place to stay. It's super cute and very clean. As explained in the listing it is small, but the space is well set up and doesn't feel cramped at all. The French doors opening to the enclosed patio open up the space really nicely too.
Had everything we needed to make some basic meals and be comfortable.
This location is really great if you want to get around on foot. We walked around Little Italy, to Gaslamp, the waterfront, Balboa Park and up around Hillcrest. Plenty of food, coffee etc nearby.
The neighborhood is very quiet. The airplanes are the obvious exception but you can really hear them everywhere in SD it seemed like. They do seem to stop at a certain point at night and never woke us up.
