Susan was welcoming and the apartment is in an absolute gem of a location. You could spend weeks here on foot without exhausting your dining options. Add a car to the equation (with the super convenient parking) and the possibilities are endless. North Park is a perfect hub for a San Diego trip - a quick drive to the zoo, downtown, and the many vibrant neighborhoods and beaches making this city a stand-out destination.
The guest house is a cozy size but we never felt crammed. Susan did a nice job maximizing the space and providing hanging space, a desk, and other little touches to make you feel at home. Very nice bathroom (though tiny sink!) and awesome shared patio for hanging out. Our only quibble would be the bed, which is a pullout sofa. The mattress is rather thin and sits on elevated boards, so this results in a fairly stiff sleeping situation - particularly if you weigh enough to exhaust the mattress's give. A TV would have also been a welcome addition to the room. That being said, with a proper mattress I would recommend Susan's place emphatically (and still recommend it highly for shorter stays).
