Hi, and welcome to the forum bellboy!
I've been to
Greece also (Pefkos, Rhodes to be specific) and I can assure you that
Icmeler is very different from Greece. The all-round ambience of the place is much better imo, it is less expensive, it's cleaner and more pleasant looking. Icmeler is a little jewel, it can never become big or brash like it's neighbour, Marmaris, as it's limited by the constraints of the sea and mountains, so it will always retain that village charm whilst still providing a wealth of activities, bars and restaurants, etc.
You just can't fail to love the place itself, the rest of the holiday is what you will make of it
