This is a great apartment, even better than in the pictures. The apartment was very clean, Devrim and Şule met me in person and took care of useful little things - capsules for the coffee machine, hygiene items, drinking water for the first evening etc. Let me note, apartments are located on the 4th or 5th floor (did not counted, sorry), and the house has no lift, near the house a lot of stairs, ups and downs - it was OK for me, but be ready.
Devrim is a very intelligent, kind and caring host. He was answering me very quickly and helped me with all my questions.
During the vacation in Istanbul I lost my documents, and Devrim was helping me look for it and call local numbers. We found it!
I am very, very grateful to Devrim and recommend cooperation with him and this apartment to other travelers.
