Wr had a nice experience in the accomodation. One highlight is the rooftop terrace from which you can enjoy the sunset and get away from the busy people. another are the high quality mattresses. communication and instructions were superb and helpful.
though you should expect the flat to be noisy. it is directly besides the street leading to the Galata tower. if you are a light sleeper you might consider earplugs. but that is the price for the central location.
