I booked two private tours at Izmir (Ephesus etc.) and Istanbul (the works) with Byzas Tours / Tours Istanbul. Their service was impeccable. Booking was a breeze and the actual excursions went perfectly. Very knowledgeable guides, practically brand new vehicles, punctuality, no hidden costs. If I could, I would even attribute the good weather on the days to them but obviously, that was just good luck.
