Mr. Hikmet is a really nice person, we arrived at 5.15 in the morning, hikmet save us the trouble with airport transfer and kinldly let us put our luggage in his office (only one building from his airbnb place) before check in time (02.00 PM). The apartment is just perfect, comfortable, tidy with 3 bedroom, 1 kitchen, 1 bathroom, and the most important walking distance to many famous & historic places. it's more that enough space for 4 of us.
Totally recommend Hikmet and his appartment.
