We had an amazing time staying here! Location, location, location. The pizza place that's walkable - Giant Pizza King, I think? - is worth your time and dollars, and short walk (package store has medium selection of local beers). Sushi Diner is a short drive, next to Shaka Coffee, and both are affordable and delish. Sushi Diner had HUGE portions for the cost.
We didn't waste our time at Mission and made the drive to OB, only about 15 mins with traffic. 15 min to downtown, 15 min to Coronado, 15 min to Sunset Cliffs.
This place is the perfect spot for you if you just need a place to crash after enjoying beautiful San Diego each night. We fit an air mattress into the larger room and fit a family of 4 :)
Parking wasn't an issue for us, but we mostly had access to the driveway. Worth checking with your hosts!
