The apartment is great and silent, as the bedroom is not on the street. Maybe the view from the bedroom - window is not great, as you look DIRECTLY to a construction side. But you are in Istanbul to visit the town of course :-).
Communication was well! You are right in the center of Istanbul. Maybe for "beginners" it could be a little bit strange that site, because it's a little bit the "raw" site of Istanbul :-).
But I can recommend it.
