Awesome apartment and very spacious for the 6 of us. Although we were slightly confused as to which street to turn in, Aslan and Gulner made sure that we got there safely. They even sent someone to come look for us on the street. The house was very clean, well maintained and well equipped with more than what you will have in an average apartment. It is located quite close to the Blue Mosque and the Grand Bazaar and easy to get to and from the main airport.
Would recommend this duplex apartment for large group of friends or family travelling together to Istanbul.
