Overall very nice stay! Location is great if you want to go to nice restaurants and cafes. Very easy to travel around istanbul - 10 minutes away from the ferry and metro station, bus to/from the airport.
Flat is located on the second floor so it's easy to come and go as often as you wish.
Flat is big, furniture is nice. All appliances are in full working order. Flat had enough lighting and you could easy choose how much fresh air you got because part of the windows have a special latch to open for ventilation
