Sahin is an amazing guy,he is very helpful , he deserves to be a super host.
the flat itself is in an old building but it is very beautiful and full of all amenities you might need, I felt that I am one of istanbul's citizens, the flat is much better and bigger than photos, the only thing is the bath room is narrow but ok , it is very close to Taksim and Istiklal street (5 to 10 min walking)
WiFi is so speed and TV is smart ( Netflix is available :D)
I like the balcony so much.
We really liked and enjoyed our stay there and the most important thing is sahin and how he was very welcoming host.
