Two things that make this a five-star review:
1) Great hosts -- When we had an issue with a cooler (100% user error), they were over almost immediately to assist. Caroline also showed up to deliver an additional boogie board (we only had three) as soon as she learned the previous guests lost one. We were pretty happy just to have three boogie boards, but the addition of the fourth one was a pleasant surprise (and we enjoyed it very much)
2) Well stocked -- In all my visits to San Diego, I have never had everything I needed for the beach (because who has room to pack all that)...Caroline supplied not only boogie boards, but beach chairs, beach towels, beach toys, beach umbrella and a wagon to haul it all there.
My only suggestion is to bring your own toiletries if you are staying for more than a few days. The cottage is .3 miles from Ralph's (Kroger), Sprouts, and CVS, so it is very easy to buy what you need, but everything cost extra in California. Small travel size shower stuff is provided.
