Spent a week here in July. Location is fantastic, close to restaurants, Balboa entertainment zone, and 30 seconds form the ocean. Unfortunately we were there during the hottest part of the month and with no A/C we had to keep the windows open at night and the front of the house faces the main street Mission BLVD that has lots of late night, and early morning traffic and pedestrians on foot, skateboard, and bikes that kept us awake at night.
Vince our host was fantastic and this is no reflection on him, just want to make anyone aware of what to expect. As far as cleanliness, proximity to the beach and entertainment - absolutely fantastic. I would definitely rent this in cooler months but in July will look for places with A/C in the future.
