Alper was a great host. Responded very quickly and answered all of my questions during my 10 night stay. Apartment was clean, modern, comfortable, well equipped and well laid out. Main bedroom with en-suite has a very comfy bed to sleep. Living room with very nice and comfortable 2 big sofas and a dining room table was very welcoming. Oh balcony was also great to have morning coffee and some fresh air. Location was very central, lots of restaurants, cafes, grocery stores, pharmacies etc. was around 5-10 minutes walking distance. Marmaray(Suburban train runs between european and asian side of Istanbul) train station was around 10 minutes away from the apartment. You can easily go anywhere in Istanbul once you hop in this train. Lots of interchange stations to help you to move around the city. Before I forgot I must say building was very quite and peaceful. Overall a wonderful place; I would stay here again easily!
