I enjoyed my stay at Berkan's place from day one. The apartment is clean and the room is spacious. he has two cats who are adorable.
Kadiköy is probably the best place to stay in Istanbul. It's outside the typical touristic areas. Here, the locals live. There's not much there for sightseeing but instead more for eating and enjoying life. hundreds of restaurants, cafes and bars wait to be discovered and dozens. To the West, take a walk on the beach. In the North is the public traffic node: bus, metro, ferry. Within 10min reach.
I eill come happily again. Come and see.
