I was there a few summers ago for spring break. Don't really remember too much about exact place that we stayed because I was consistently drunk. It's a drive from Rosarito...which I think is a good thing ebcause you stay away from all the regular tourist spots. It's pretty scenic and overlooks the ocean. The best part of it was the lobster. I think all the lobster spots are pretty much the same in terms of the quality of lobster. For about $10 you get a lobster to yourself, beans, rice, tortillas, a shot, and a kool-aid like margarita. Lots of street performers and vendors when I went so it gave us a couple of things to do.
Hope that helps.
