We had a wonderful stay. The view is amazing, the location itself is just perfect. Eyüp is a great host. He met us in the middle of the night, helped us to get our super heavy luggage to the 5th floor, gave us really great recommendations about places to eat, ordered us a taxi when we were leaving and let us check out late.
The only think you should consider is the noise from the street, though if you close the windows it’s not that noisy and anyway everything gets more or less quite closer to the midnight.
