One of the worst experience ever. Waiting for check in 1,5 hour even check in start before 2 hours, I didnt get room which I paid because there was some an "electricity issue", I get for the first night room without window (and its summer and very hight temperature in Istanbul) and also water was dripping from the climate. Also in my new room was problem with electricity. Second day when I came and ask what is with my room they said can I spent one more night at room without window and I said no and that I want my money back after that they offer me another room which they have in another building which is also smaller that I paid first. Bypass as far as possible
