Sertac's place was just as it was advertised. It was very clean and tidy. The shower was perfect. Having the washer there was also very helpful as I stayed for over two weeks. Sertac was always available on WhatsApp and responded very promptly to any inquiries. He spoke English very well and I had no problem in communicating with him. The location is perfect for a new visitor to Istanbul. Overall I had a very pleasant stay at his place.
