We were a group of nine people and booked two flats in Murat's accommodation and had a great time there. The accommodation is centrally located by the Galata tower and there are many lovely restaurants and shopping facilities nearby. The city centre can be reached within a short walk.
Murat was a great and very helpful host. He arranged the airport transfer for us and helped us to carry our luggage into the flats. He also asked frequently whether everything was ok or whether we need anything.
