We loved the flat, my partner was here for a convention at the San Diego Convention Centre and I was here on holiday and it was perfect for our needs.
Location-wise, it's walkable to the Gaslamp District and even easier if you have a car as there is free street parking. There are also some shops and coin laundries nearby which were very handy.
The flat is really nice, and was clean and well equipped. We also loved the bunny farm underneath. Wifi was slightly slow but was sufficient for our needs. Would definitely stay here again if we ever come back to San Diego.
