Rita is a fantastic host, I do not even know where to begin.
The house is fantastic, clean, and very well equipped. It is also very conveniently located, a few minutes' walk from the UTC Trolley station Blue line which goes downtown, and down to the Mexican border. In front of the UTC Trolley station, there is the MTS bus station serving the whole area. Furthermore, there is a shopping mall with all the possible stores needed. The location is ideal for UCSD students, faculty, visiting, and more generally for people arriving in San Diego for the first time!
Rita was very generous and took the time to explain plenty of things about the city, giving useful advice. We always had interesting conversations about the most diverse topics, she is extremely knowledgeable. Moreover, she drove me around the city a few times to show some of the main attractions. Last but not least, she is an excellent chef and she shares food all the time; we had plenty of delicious homemade ice cream.
I would definitely recommend staying at her place.
