Mehmet’s apartment was an ideal place for my wife and I, 68 and 65 year old Canadians respectively, to stay during our 2 month visit to Istanbul.
It is very centrally located making it relatively easy to get around using public transit. It is on a busy street chock full of multi-storey residential buildings with commercial space on the floor level. That provided ready access to grocery stores and restaurants and the like but we never heard any of the street noise in the apartment.
It is well laid out with the bedrooms farthest from the front street. It was well furnished with a well set up kitchen and a handy washing machine.
The very few times when minor issues arose (e.g. an interruption in net connectivity), Mehmet’s responses were timely and helpful.
Highly recommended.
