I've been a constant traveler via airbnb since 2014 and here is my honest review:
The pros:
Location is perfect, close to everything. Street full of cats! We've already missed the street:)
The apartment is huge
Bosphorus view
Very quite to sleep (rare for Taksim)
Cons:
The bathroom is tricky and you shower very carefully
The wifi does not cover the large bedroom :(
No space in the closet
But other than that everything was really good and I would recommend the place for a short stay.
