I stayed in Murat’s place myself and my family. We enjoyed our stay in Murat’s place.
The place is clean and Murat, provided simple toiletries (shampoos and conditioners ) for our stay.
The location is 6 minutes walking probably less to T1. Also, the location is a bit busy so expect to hear some noise around noon time and afternoon, but if you are discovering Istanbul at that time and not sleeping you will never notice it.
The other thing, Murat was so respective and responsive answered all our questions about our stay.
I definitely recommend Murat’s place for your stay in Istanbul
