I know Istanbul very well and I can say that the noise level is normal for the location because there are building sites everywhere. We weren't really distubed and found it acutally quite peaceful. I loved the proximity to the metro and to a selection of very good bars and restaurants. The host, Coskun, always responded to our requests and was always friendly even though I accidentally triggered the smoke alarm. The apartmen was full all the amenities we could possibly need. I recommend.
