We stayed in San Diego for a few days and were excited to stay in the middle of the gaslamp district. The AirBnB is in a more residential area without a lot of tourists, but is about 5-10 minutes walking distance to restaurants. There are a lot of seemingly vacated buildings and homeless people who loiter around the area.
Check-in and communication were excellent, and the AirBnB was extremely clean and spacious.
However, the walls are extremely thin and we could hear neighbors playing loud music and having conversations. The internet connection was poor as well.
Finally, the tram runs right in front of the building. Though others in reviews said that the host-provided ear plugs helped suppress the sound, it did not. The tram was extremely loud and runs frequently throughout the entire night, and you can feel the apartment building shake which was very disruptive to our sleep.
It is a good place to stay if you are a heavy sleeper on a light budget, but I would rather spend a little more money for a quieter area next time.
