In April there were 6 of us with Levent. We visited the House of the Virgin Mary and Epheus and the cost (excluding tip) was $30 per person. $30 per person was to include seeing a museum too but we all opted to cut the afternoon short so we'd have time to SHOP! (we prefer 1/2 day tours over full day anyway). We were all very very happy with Levent.
Besides being very nice and so knowlegeable, I was impressed that he always carries a bottle of water with him around Ephesus and pours little cups of water in various locations for all the stray cats that live there. Now that is my kind of guy!!
