There is no AC. It is not listed that there is AC, but it is also not mentioned that there ISN'T AC. We visited during a heat wave and it was very uncomfortable the first night. The location was AMAZING. We were a jump away from the beach and spectacular views and could walk to some great local spots. The sofa bed is more of a full size at best. Tempurpedic topper made it comfortable. Shower is phenomenal!
It's good to know that most of the town closes early (by 9-9:30pm). It made it difficult to get back for dinner if you really wanted to stay late at the beach. We went to The Shack for one of the only places open late and had a good meal with decent drinks. Otherwise, head to Pacific Beach.
All in all, Cy was a great host and the stay was very relaxing and enjoyable. Cy gives great recommendations and lives downstairs if you need him for anything.
