I stayed here for 4 nights with 3 other friends. Really spacious and comfortable apartment 10 to 15 mins walking distance from the most happening spots in Nisantasi and Besiktas.
Ekrem was a great host. He was quick to respond to all our questions and even recommended a list of restaurants, cafes and bars that we visited and really enjoyed.
There's a lot to love about the apartment but for us the location and comfort really stood out. Will definitely try to stay here again next time were in Istanbul.
