Really an ideal place to stay in San Diego, with kids. Plenty of room for us and our 4-year old son, could have easily accommodated another few kids. The proximity to the beach -- along with all the beach fixings you need (chairs, toys) -- really cannot be beat. And there's so much else that is within easy walking distance. We checked out the Pacific Beach farmers market, just a few blocks away, and totally loved it! (note this is only on Tuesdays). Also, a ton of great restaurants within a very quick walk. Trader Joe's, super close.
Highy, highly recommended for families staying in San Diego. :)
