I wouldn't say he was rude, but he was not friendly.
although the house is the luxury neighborhood of Istanbul, it is the underdeveloped part of that neighborhood. The last five minutes of driving distances to the house is cobblestone, super narrow that only one car can pass, and the very steepy. if you are not confident in your driving skills don't go there by your car.
the house actually has a nice view as shown in the picture.
the problem that had with Hakan that contacted Airbnb about tu and canceled my stay was for the parking. Although the description says " on premises parking", the house has no parking. The last response from the host about it after cancelation is below:
"Airbnb doesn't say there is a dedicated parking lot in the building. It says you can park for free on the street and in front of the building. if empty"
