Megan and Tatiana are stellar hosts and perfect temporary roommates. The location of their house is convenient for all things SD. They welcomed my dog and I with warmth, and made sure I knew I could feel at home there. The bed is super comfy, the wifi was great for remote working and streaming, and I felt 100% safe in the neighborhood.
The only thing I'd like to mention for those super introverts is that during the weekend, Megan and Tatiana had a lot of visitors coming in and out. Granted, it was a birthday celebration so may not be a typical occurrence. Everyone was very friendly and they were mindful of noise - but I wanted to mention it in case you are expecting a very quiet and reserved household. BUT I enjoyed talking to locals and getting small doses of socializing, so it didn't bother me!
Overall, I would definitely recommend staying at Megan and Tatiana's place while in San Diego. Great value, very warm hosts and really good communication.
