This was a great rental for our group, which included four adults and two toddlers (<2yo). Location is great - quiet neighborhood not far from downtown La Jolla. The neighborhood itself was fun to walk around, looking at all the gorgeous houses and of course walking along the beach, which is just one block away.
The apartment is spacious and very kid-friendly. I didn't feel the need to baby proof anything. (Hard to tell from the pictures, but one of the bedrooms does have a bathtub.) Lots of beach equipment provided, including beach mats, plastic buckets/shovels, umbrellas, and more. And, a huge movie selection for after our kids went to bed.
Bluewater was super helpful, and even provided some referrals to local agencies that do vacation rentals for toddlers - which basically meant we didn't have to cart our car seat and pack-n-play through the airport. It's a small thing, but greatly appreciated.
