Generally we enjoyed our stay in Apartment. The flat is huge, perfectly located in Kadıköy (close to metro and bus, to walking streets and ferry station, but quiet). Apartment is well equipped - TV with Netflix , YouTube etc., good wi-fi speed for working, washing machine and dishwasher.
Just one moment we would like to highlight: apartment condition is not new - kitchen looks very shabby, shower joints with some black spots like mold or something. We are not so demanding persons, and for us it was a good compromise in price/quality, but for more squeamish persons it could be a problem.
