Portinax or Peurto San Miguel are fab for families couples and kids both are north of the island so no pumping noise from space night club Very very pretty locations
or if you want more stuff to do but still in a family location then Es Cana is nice I stayed at the miami hotel ( right on the beach all inc) with ds and her two girls 4 13 and had a great time You can walk across the beach and there is shops bars restaurants but its all low key walking distance to the hippy market and you can get buses from there that go to most of the island
I've been to all three places and they are all really nice
Portinax I've stayed at the El Greco ( years ago) and the Presidente with just me and dh last year totally over ran with kids as it was summer holidays but they have the thomson kids club which looked great for kids i played bingo for the first time ever and one 175 euros (lol ) rooms are very basic though but they have bunk beds in the rooms so easily sleep 4 with plenty of room ( we used the bunk beds for our suitcases)
We went to Portinatx in the summer holidays with a 9 y old and it was a quite small resort - family friendly and quiet enough for us with a lovely safe beach/bay area. we went AI and the hotel had an added bonus of its own small water park. There were a few nice restaurants and bars but I'm not sure what the food shops were like if you were self catering - I would def go back there.
Looking at cheap flights for the summer and considering Ibiza. Have never been before and am travelling with a 5 and 6 year old. Are there any nice quiet family areas of Ibiza or is it all party party?
