I stayed with my boyfriend from 20th to 29th of September in the flat. The flat, although very small, is cozy and well organized. The best is its location - 10 min walk from Taksim and 5 min walk from the tram stop.
The only not so cool thing about it is that, because of its size, it doesn't have window. So, it can get very hot!

I didn't meet Akin personally, but he was very kind and attentive from the very moment I booked the room to the last day of our staying.

Enjoy your stay! =)
