When I was a kid, my grandmother lived with her parents in Santa Monica and I remember visiting her. It was magical! I want to repeat that experience with my partner and two step-sons over the summer. We'll be renting a vacation home for a week in either Santa Monica or Venice beach. I know you can walk to one from the other, so not sure if there is a big difference where we stay (please correct me if I am wrong). None of the condos or houses I've seen come with air-conditioning though. Owners are telling me it is not needed, even though we will be traveling late-July/early August. Is that true?
