We really enjoyed our time at Zeyno's house. It is super cozy with lots of interesting details and at the same time has everything that you need while traveling. The location is great: in a walking distance from the tram stop that takes you to all the major sights in Sultanahmet, also not far from good restaurants and bars, but very quite at night. Zeyno was friendly, very helpful and quick at answering our questions. Highly recommended!
