If you have a limited time in İstanbul and really want to see the ruins in and around Ephesus, I can provide a full day trip for you as well. You can fly into İzmir in the early morning. We can do full day trip to Ephesus including the site itself and the house of the Virgin Mary, Temple of Artemis, St John’s Basilica. In the end you will be transfered back to Izmir Airport for your evening flight. It is that easy.
