I have. Nice little fishing harbour. Town square and a market once a week. From what I remember(5 years ago!) there was plenty of restaurants and the sandy beach stretches the whole length of the main drag. Bars on the beach too.
It's definitely not Palma Nova !! Much quieter and less neon around. The big complex, Pollentia Club, is a fair way out of town and the beach opposite (across the main road) not so nice as further along.
dont know were we're staying its sleeps 8 is all i know and the owner lives downstairs so maybe its on first floor and they also have something sleeping 6 above..so in light of that, it sounds like a private 3 story apartment, must be huge!
we went to palma nova in feb, so there wasnt much neon straw donkeys etc..but beaches were fab..would have liked to have gone back there, but we enjoy going with these friends as dd would enjoy it more with her dd !
Puerta Pollensa was nice when we went there, definitely semed quite child-friendly - lots of restaurants right on the beach so you can watch them run around while you eat, etc. Big supermarkets and so on, big market at the weekends, lots of bars and cafes. We stayed at Pollensa itself, which is about 5 miles inland, and I'd highly recommend that as well, tho possibly not as much fun for kids - a real little Mallorcan town, very pretty, lovely town square.
