During the stay everithing was ok.
The flat was the same as on Photos.
For the brif summary this type of accomodation is good for the long stay.
There are no usual problems for Istanbul accomodation as central heating, water pressure and Wi-Fi speed.
So You can consider a stay if You need a place for work and a place which is quite close to the main streets and evening entertainments.
Personally thanks for the Berk, he was helpfull and made during follow ups in order to check if everything is ok or not.
