Efrain's place was excellent. Right next to Balboa and SD zoo. Central to a lot of local restaurants as well which makes it more convenient. It's also 10 minutes away from downtown. The place itself was very clean and safe, and there were snacks in the property too like popcorn and chips! Really cool. Never got to meet Efrain personally but I did get to meet his dad and he was extremely friendly. Would highly recommend this place if you're looking to explore SD.
