I would recommend everyone to stay at Selçuk's house. He is a great host and really helpful and attentive to the needs of a traveller. Also he was available for some nice chats and tea and telled me some interesting things about Turkeys culture. The appartment was as described clean and really comfortable. The private room is big and luminous and in the night it is really calm. The neighborhood is awesome, you can get everything, there is also a fresh market and a lot of restaurants and cafes. Within 5-10min you reach the seaside and there are also the ferry and metrostations to reach all the other parts of Istanbul. I really recommend to take the ferry, you will have a great view over whole Istanbul and it is only 5TL so you can get easily to european part of the city. Teşekkürler!
