Taner's place is near the Taksim square just 5 minutes walk from it. Though you have to walk a very steep ramp before reaching the taksim square, this might be easy for young aged people but difficult for the elderly, as we were travelling with our mom, she found it difficult to walk this steep incline.
Taner's communication is very good, you can text for anything and they would reply you very quickly.
The place is like a hotel, though i have to say that the room that we were given for three people was not the one shown on the airbnb post, the room didn't had the sofa that was shown and was quite small actually it was the room for 2 people they just placed an extra bed for third person, was bit disappointed for that, but as we were staying for a single day, the time passed away. I would suggest the other travellers to make sure that the room given to them must be the same as the one in the photograph.
