We had a great stay here! The apt. is clean, well kept and very conveniently located- not too far from the activity of Sultanhamet and Beyoglu, but not right in it- which was perfect for us!
Fatih was very helpful and welcomed us when we arrived, he also assisted us with our transportation plans within Istanbul, which was a great help.
Overall, we had a great stay and would highly recommend the apt. and neighborhood.
