Errm, I would stay there again, because we didnt mind the families and stuff, but you couldn't really sleep off the night before around the pool, if you know what I mean!
I liked Playa D'en Bossa because of the location, near to Ibiza Town and of course Bora Bora and Space up the road. However, it wasnt great for restaurants or nice bars, you generally have to go into Ibiza Town for that.
Have a good holiday btw!
