I rented Murat's apartment for 3 nights, I had a very good stayed! It is like a big hotel room with a large window and plenty of natural light. There is a big sofa and a good AC which is very nice after a long day of exploring the city where you can truly relax. The surrounding has some construction going on during the day while I was there, traffic is noise not so bad, but it was quiet after 11pm or so. The apartment is located on the down hill area, be physically prepared. It is about 15mins walk to Taksim Square, and next to Cihangir a really cool place for bars and cafes.
