We booked this house during an apparent heat wave for La Jolla. We booked months in advance and knew the house didn't have AC but thought in Sept it would be fine for San Diego. When we arrived it was 85 degrees outside and it was so hot in the house, we opened all the windows, turned on all the fans, we even went to ACE Hardware and purchased a $200 portable AC unit and the house was still showing it was 90 degrees inside. We were all sweating and had a one year old so it was just too dangerous for the baby to nap or sleep in and we had to leave to go somewhere else. Karen was so kind and refunded our money minus the cleaning fee which we appreciated. The house was really neat and we would definitely want to stay during cooler months but would highly recommend an AC unit for the house or don't go during hotter months.
