Just joined and first vist to Icmeler

Will be visiting Icmeler for one week in August staying at the Bonjour apartments. My son and I are thinking about renting a car for two days for a trip to Ephesus and Pamukkle(? spelling - apologize). I live in Florida where the land is flat and wonder about driving through the mountains. Should this be a concern? Would appreciate comments on driving to these areas and also the Bonjour apartments. We are so looking forward to visiting Icmeler, especially since reading the topics on icmeleronline. Thank you so much!!!! Carol
