You should look at Sunset Beach Club - its in front of Blue Green, and therefore right on the beach. people staying at Blue Green have to walk past it to get to the beach.
It has 7 pools plus several kiddies paddling pools and plenty of grass. There is also a small children play area (slide, swings etc) on the beach itself.
Our grand children love it.
It also has an on site bar, restaurant and shop.
I'm sure if you Google "Sunset Beach Club Turkey" you will find lots of apartments to rent - there are all sizes from 1 bed aparts to 5 bed villas.
