Handan's place is very lovely and cozy with a fantastic view to Bosphorus. The location is great, in the heart of Cihangir, where you can find a lot of cafes and restaurants.
The apartments have everything you need: washing machine, kitchen etc.
The wi-fi connection is very good (which is always a problem for Turkey), I had a few Zoom calls and it worked well.
My favorite place was a chilling zone with a red chair on a balcony.
So I highly recommend Handan's apartment for staying.
