Please look up the Welk online for a better and more detailed description. The longer you rent it the less the cost per day. The calendar may show open because this unit or other units may become available last minute so just email me to confirm that it has become available. Best with a 3-6 month request and 4-7 day duration. Also if you are flexible with other San Diego locations I have a better chance at finding you a location to stay and enjoy. The two-bedroom two-bathroom unit sleeps 8. The one-bedroom one-bathroom unit sleeps 4 and has full kitchen, full bath, living room with a pull out sofa, dining room, washer and dryer. There is plenty to do on site.
