I have been everywhere and we always hire private tours (for my wife and I). Never I have found such professionalism in a tour provider. 5 Days is not enough for Turkey private tour. We spent 2 days in istanbul, then we flu to Capapdocia, Izmer (Ephesus) and Hierapolis. In every place we had an almost new Mercedes Van, Driver (very decent guys) and the tourist Guide (2 of them with 2 college degrees). Best hotels Istambul Ritz Carlton, Cappadocia Kayakapi and Kusadasi Charisma de Luxe.
