Very nice guest house in quiet neighborhood. Zoo is within walking distance, a few restaurants are as well, but most everything else is a bike ride, drive, etc. It is centrally located for the San Diego area.
The home is one of the nicest airbnb I have seen. It is obvious it has been recently updated with top quality products (e.g. a lot of crate & barrel items). There were two adults and two children ~4 and 1 and the place worked wonderfully for us. The guest house has a shared wall with the main house, but we never really heard anyone.
Really it was the less noticeable details that were especially nice. For example, the host quietly turned on the outdoor lights when we were outside and it was starting to get dark. We never would have known to turn them on ourselves.
Would highly recommend staying at this beautiful guest house.
