We thoroughly enjoyed our stay at Donna's place. As described, the garden house is a small guest house in the backyard. It was easily accessible through a gate on the side of the house, which also felt very private. The backyard is lovely, with a relaxing water fountain and outdoor seating area. Donna came to greet us and was very friendly and accommodating. She even went to the trouble to set up a separate bed for my friend I was traveling with. The little touches (such as cold water bottles in the fridge and homemade brownies to welcome us) really made our stay feel extra special. The next time I visit San Diego I will definitely be checking this space for availability!
