I had a room on the ground floor, windows set to the building facade, because of this it was little bit dump. Airing it did not help much.
With open window, it was quite noisy.
The room itself is pretty small, only bed and a chair were usable, there were also wardrobe I could not use.
Room was not lockable.
Overall, the basics were there and it was pretty cheap, so you get what you pay for, but I stayed in significantly better rooms in Instanbul for the same price.
