As others have mentioned Mutlu Bulut, I also wanted to share my experience with him. I just finished a Mediterranean cruise a few days ago.
Mutlu was very professional, and over email ([email protected]) he helped me plan an itinerary that fit within the time I had at port. He made the whole process easy and stress free. We ended up touring Ephesus, the Terrace Houses, the archaeological museum, a weaving school, and a great local restaurant for lunch. If we'd had more time, he could also have included the House of the Virgin Mary, the Basilica of St. John, and other nearby sites.
The tour itself was exceptional. Mutlu was knowledgeable (full of interesting facts) and entertaining the whole time. I was traveling with my 12 year old twins, and he was great at engaging them so they had fun too.
He went above and beyond, making sure we got great photos and stayed okay in the heat (we were there in late July and brought sun umbrellas, but it was 104°F/40°C that day). He tailored the tour as we went, based on what caught my kids' interest, and gave us free time to explore places like the Library of Celsus on our own as we wished.
He's a wonderful tour guide, and I'd absolutely recommend Mutlu for a tour of Ephesus and the surrounding area. Kuşadası was our favorite day of the whole week-long cruise, thanks to him!
