İstanbul is a very busy city, but we had a very comfortable and quiet/peaceful stay in this place. It also felt very secure. We didn’t have any problems and the host is very helpful. Can highly recommend it. If you are not used to it the prayer call from the mosque might wake you up during the night, but to be honest you will have that in almost all places in Istanbul or in Turkey for that matter, and for me this was therefore no problem.
