Apartmet is great, is independent and have everything you need. You can take the train from the airport and walk arround 10 minutes. The neighborhood is really quiet and safe, nearby restaurants are good and the supermarket close at midnight so this was fantastic to me. Really well comunicated by train or subway that you can reach by walking.
Serkan is an amazing host, he's always available and pending if you need something, the weekend that I stay here he had a family reunion and he bring me some food to the apartment
