It was a lovely experience staying in Vahibe's home. Her sister helped me to check-in though Vahibe was not home when I was arrived in Istanbul, and she always did her best to make me comfortable during my stay. She even came out to pick me up when I was in trouble with riding taxi in Taksim square.
The room was super clean and silent, also the bathroom was perfect with high water pressure.
I'd love to highly recommend this bnb to any friends who want to visit Istanbul!
However you'd better mind that this bnb has no elevator, as it says in the introduction. Also you have to go through many steep slopes to take buses, subways, and taxis. Make sure you have less luggage if you want to visit here!
