Gursel has been a great host!
He was very nice and helpful and even if his english is not perfect he did everything possible to satisfy our needs.
The room and the bed are very small but the price is cheap so we didn't complain. The house is confortable and from the terrace you can enjoy a very beautiful Bosphorus' view.
The postion is perfect, just near the Galata tower right in the center of Beyoglu!
