Unit 1 is a perfect space for a couple or a family. It was enough space for my 4 year old son, my husband, and myself. We even had enough space to entertain family in the living room. The backyard is closed off and safe for little ones. All you need to do is pick up groceries and enjoy your vacation because this place is close to the airport, San Diego zoo, Seaworld, downtown, and the beaches. John is very responsive. The guy that maintains the grounds was also welcoming. You will not be disappointed. Thanks John!
