I highly recommend staying with Katia during your visit to San Diego. I had a very positive experience staying there. The apartment is very modernly designed and new and clean. She was also nice to talk with and provided more things in her Airbnb than other places I have stayed (e.g., access to bikes to ride and board games). For European travelers, it looks like she has outlets so you won’t need a converter (and also has US outlets). Just note the wifi is spotty (for streaming like Netflix) and there are some ants, but even with these two minor drawbacks, this is still one of my favorite Airbnbs to date. I hope to return and stay there again!!
