The location is great; you're a short walk from Ocean Beach, the Dog Beach, downtown Ocean Beach, and another group of restaurants around Voltaire street. You can also easily get to grocery stores, liquor stores, etc. and there's a nearby dog park. The owner is also dog friendly and allows small dogs to stay there.
The courtyard is very nice and has a grill available if you want to use it. The lounge chairs and lights make it a very relaxing setting and a great place to spend an evening. The inside is renovated and very clean as well, and the host is very responsive. The kitchen is up to date and the appliances are quite nice.
On the downside, the location is pretty noisy. In the living room you'll hear the conversations of each group that walks by, and even in the bedroom you'll still hear louder cars, stereos, and motorcycles. Also, there are pretty intrusive little black ants; I don't know if that's specific to this house or just a general issue of Ocean Beach (it's pretty warm and humid there). You'll have to be careful not to leave anything around that might attract them.
Also, the host has some pretty strict rules, so make sure you're okay with that before booking.
