We had a lovely stay in Istanbul, and the apartment was great. Walking distance to Istikal street, right next to Galata tower and close to communications to Sultanahmet. Hüner was very helpful - we got to check in earlier, and when we we had a problem with the water boiler it got fixed quite quickly. The only thing to consider is that the apartment is on top of a hill and the area is quite noisy even at night, but as we didn’t mind we had a great time.
