Me and my girlfriend really liked the place. It was spacious, 2 bedrooms to sleep and 3 other rooms to chill, including the dining room. Also the a/c helped to bear the hit. The view from the windows from the top floor and the atmosphere of "real" old Istanbul - loved it so much.
And Dilek is a lovely host. Although we've sent request on the same date of arrival, she managed to prepare the apartments and settle us in.
