The appartment is very close to central square of Besiktas, like 2min. Very convenient for transportation, by bus or ferry to Asia etc. Taksim valkable distance. Appartment is ground floor, and noise isolation is so so, even with windows closed (I used ear buds for sleeping, my wife was ok without them). Be sure to open windows whenever possible, especially if it was raining (to force ventilation). Bed not very comfortable. The appartment is after renovating, everything is new. The host was helpful and flexible. He was kind to agree on shortening our stay as we needed to fly out earlier. He paid back for the nights we had not used, even thou he was not obliged to. We are thankful :)
