The house is perfectly located, very close to the center but outside of the main streets. Cem has been very welcoming, available and flexible. The house is very clean, with everything that you need.
The only issue we had is that the house is close to the mosque and the ground floor is sometimes rented by other guests, which can be noisy in one of the rooms of the house - but I am very sensitive to noises. Other than that, a great stay and perfect get away from Istanbul!!
Thanks!
