I would highly recommend this apartment, it's cozy, has a great kitchen if you want to stay in Istanbul for a while and cook something yourself. The neighborhood is one of the best in Istanbul – clean streets, nice restaurants, a lot of historic places and museums, many vintage shops, and nice coffee places. The service and communication are also great, don't need to worry about anything, Defne, and the housekeeper will gladly help if there will be any questions.
