We spent 2 nights at Handan's place as a family of 4 and it we enjoyed our stay. The apartment is spacious and really clean. Beds are comfortable and everything you need is there. Handan is a great host and arranged everything quick and good. The only "problem" was the airco that made a lot of noise during the second night but probably this is already fixed. About the neighbourhood; it's a bit raw and less trendy and polished as the other side of Beyoglu but we didn't feel unsafe at all and it's really centrally located. So yes, we definitely recommend Handan's place.
