Great stay. Guest house is spacious with brand new appliances and recently remodeled. The pictures actually don't do it justice. It's also super private -- there's a wall separating you from the main house and the owner is accommodating and helpful (even leaves a list of restaurant and activity suggestions!).
The guest house is in a quiet area of Ocean Beach so you don't have to worry about being woken up by beach partiers in the middle of the night. About ~10 minute walk to the beach and other restaurants. Great location.
