We spent 15 days there with three kids and a babysitter (End Sept, beginning Oct). A lovely place overall!! We enjoyed it a lot. Beautiful garden, a fantastic pool (and enlightenment in the evening), and a big BBQ. All you need for a lovely stay at Mallorca. Ideal also for families, all the kid's equipment is available, and a work desk with a good chair.
The neighborhood is quiet, with a few beaches nearby, a kids' playground, and a few restaurants (Our favorite one was the restaurant in the Alcanada Golf resort nearby)
You can walk 20 minutes to Alcudia Port (albeit the second half of the path is not lovely, passing an old factory)
Subscribe to Mercadona online grocery before your arrival to buy the basics and water (the tap water is not good, a bit salty...); the delivery times are usually 2-3 days. There is a small grocery store nearby but with a minimal offer.
The only thing we didn't like about the place was the mosquitos everywhere, all day and night.
