Mr. Tayfun was very communicative. It was smooth check-in after a long journey. He kept some water bottles for us and ordered food on my behalf (as I didn't know how to order through local apps). Anyway, I paid for that food :) Thank you, Tayfun. We enjoyed our trip.
However, if you have heavy luggage, it could be challenging to bring it to level 3 because of the narrow stairs and no lift.
