We traveled from the US and stayed for 10 days. The apartment was clean, the neighborhood was quiet and most importantly we feel safe. There is two AC units in the apartment and electric blinds on all windows which helped keep the place really cool if you keep them down. I mentioned this because most Americans probably don’t know what that is. You have everything you need the metro is at walking distant. When you get to the airport I suggest getting a Türkcell mobile card for your phone they have one for tourist and also the Istanbul metro card. Make sure to pre-pay some money on your metro card. There is an app that you can download called (Bi taxi). We use google maps to get around with the metro. Meltem was always there for us if we needed anything.
I would recommend everybody who wants to visit Istanbul and stay in a nice quiet and safe neighborhood with more locals then Tourist to stay in Meltem’s place.
