Hi
We stayed here and it was perfect. about 5k from the beach (up a fairly serious hill). Near the markets and the main town of Hisaronu. Close enough to everything to walk there in 5 minutes, far enough away to be quiet when you are in the hotel grounds.
Bus to the beach (dolmus) is about 90p, pint of draught Efes £1.80, and the food in the hotel was out of this world. September will be quiet as it is end of season, but your still guaranteed 30 degrees and sunny all day every day.
We went as a family group of 11 in September, and we are all agreed on going back this year or next.
If you are thinking of going then chuck Oludeniz, Fethiye, Lycian Way, and Ghost town into google and have a look.
