We were attending a conference at the San Diego Convention Center. This place was convenient for our needs! Only a 12 min Uber from the convention center. There is a well-used couch for a third guest and an additional mattress was also provided (very accommodating).
Gus is an excellent host, very responsive and helpful. We needed extra towels and he had them for us immediately.
The only addition is that the alley-way is rather dark at night. This is where the entrance is located. I recommend traveling in groups if you are arriving after dark.
