Look no further in Cihangir/Cukurcuma neighborhood of Beyoglu. A three minute walk from the Tophane metro, itself one stop away from Karakoy and two from Eminonu. A 10 minute walk to Istlikal St. You can walk to Galata, you can walk to neighboring Galata or Taksim. Classic building, spacious apartment, neat and stylish. More restaurants, cafes, bars, boutiques, and grocery shops than I can count. And Eren is a superb host (pro tip: ask him for recommendations). Truly, he goes above and beyond. You will find the finest airbnb has to offer here.
