We were there for six days and it was confortable. The apartament was clear and the situation was fine, maybe a little bit far from Galata Tower but we prefered to be there because it was a safe and quiet neighborhood.
Sayda (The owner) was so nice, she explained everything about tourisim and she advised us for diferents places and transports. Also, she lent us her transport card for those days.
I recommend this apartament for people that want to travel to Istambul
