Things to know before choosing;
1)The building was old obviously and you can literally hear the footsteps of the upper floor residents.
2)The location of the building is a little dangerous, the people surrounding that place are not hospitable, and not friendly.
But the location is very close to pretty much everything in taksim so that's a good part. Room was clean although the bed sheets was a little stinky. Also there was noise coming from outside and the source is the people that i have mentioned before. It was warm. The host is super cool. Very kind. Very instructive. So thanks to her. But you should consider these before booking.
