My God, that's a blast from the past! On our very first trip to Turkey, we stayed at the Atac. It had no pool then, but it was very close to the sea, and of course, we used other hotel pools (for the price of a drink or two). It was only classed as a 2* then, but it was great. Short walk (then) into Altinkum, but we found it ok, even with 3 young children.
Atac hotel pronounced as "atach" is on the second beach very close to Tauntus hotel,Most rooms have great sea view,it has 2 outdoor pools and 2 bars.You will get to know all the staff,all are very friendly especially ilyas at the bar,i'm sure u will have a great time there.
