Good location, just be prepared to walk up a steep hill when going towards Taksim. I chose to go via Findikli and come back by Taksim so both ways it was a downhill walk for 5-6 min.
The apartment needs some maintenance and not in a great condition as it looks in pictures but the host is cooperative and very responsive he got us a new fan when we requested for a new one, as the existing one was not good and needed to use it for ventilation.
It is in the basement/ lower ground floor and will have a few stairs to go down.
