The flat was great.The area was not a touristic commercial area but a real ruff turkish one.10 minutes walk to the grand bazar and sultanahmet.For me and my friends it was perfect.There is no more hole like I read before in the comments but a normal european toilet and the internet worked also.The second day we had problems with the water.we make one call to enes and the next day everything was fine.The door and the windows are really safe so we had no fear that somebody breakes in.There is a washing machine,fridge and a hearth.
I just can say Beste Leber and thanks to enes.
