Great place and the host!! He welcomed us late in the evening, as well as checked early in the morning (6am) with us if all is good and we all set to reach out the airport and catch our flight.
The whole place is easily accessible by Uber from the airport (15min drive) making it very convinient for any layovers in Instanbul.
It is also very clean, comfortable and huge (in fact it is the whole flat).
