Isil was a wonderful host. I didn't get the chance to meet her because we were only in Istanbul for 2 days, but from day one when I booked the flat, she was quick to answer and very helpful, always there if you had a question or needed an advise.
The flat was great, immaculate and very functional, easy to reach by bus or taxi (despite what I read about the neighborhood on comments before!) decorated with taste and located in a neighborhood I would advise anybody visiting Istanbul to get to know. Balat is an upcoming area, very charming and traditional, but with amazing trendy little cafés and restaurants.
It was a perfect stay, thanks Isil!
