The flat was great- located in a quieter part of karakoy but easily walkable to a lot of the fun spots nearby. Very close to a tram stop as well that goes right to sultanahmet and a couple of the ferry stations to go across the bosphorus (also a nice walk if you don’t want to take the tram). The flat itself was comfortable and has excellent AC and Cihan was super responsive to any questions we have. One thing to note- there are a lot of stairs to walk up to get to the flat (was fine for us as we travel light but would be a bit difficult if you have large suitcases)
