As Celal and others have said, this studio is at a prime location. I walked everywhere from this place: to nearby sites, the metro station, and the coast. Worth it. I loved being able to walk around Istanbul and still be close to my place.
Celal was excellent at communicating quickly—within the hour. He sent me a list of recommendations which was considerate. He was helpful whenever I needed him to. He also left me some Turkish desserts. It was such a sweet gesture.
