This is THE perfect place to stay as a single traveler (or couple), very small apartment, BUT the most beautiful , largest terrace!
Firat is awesome in communicating and very friendly and helpful. There is a very small elevator which takes you to the the second highest floor, after that a short climb to the top floor. The area of Moda is from what I have seen, the most peaceful and beautiful part of Istanbul. A ten minute walk to Kadaköy port which takes you over to Karaköy (Europe side) in twenty minutes for approximately USD 2. I highly recommend Firat’s beautiful place.
