I stayed here for a night and it was great. The space is in a very convenient location--walkable to Downtown, Gaslamp, and most amenities. Barrio Logan is also a great neighborhood, and was my favorite area during my stay in San Diego. It's walking distance to the convention center, but not literally right next to it, so check the walking times before you book to make sure it's convenient.
The shared areas are very nice: kitchen, bathroom, shower. Despite being shared, everything is pretty private and I never felt cramped or uncomfortable. The outdoor areas are very nice too. It's great value and I'd totally recommend this place.
