My boyfriend and I stayed in the 4th floor apartment during our week in Istanbul. The flat is in the Bazaar District, a bit off of the beaten trail. If I had been alone I may have felt a bit uncomfortable walking home at night given that the roads weren't always well lit, but with my boyfriend (or anyone else) it was fine. The flat was quite nice for our needs, comfortable bed, nice shower, and well stocked kitchen. The maid was very nice and did a great job keeping the flat tidy.
