I arrived at Ahmet's place a day later than expected. Ahmet and his wife were home to welcome me. I liked the room very much, it has everything one would need (although I would add a bin). It gives unto a cul-de-sac and faces east so it's quiet and very nice to wake up to the sun shining in. Another positive point is that the bathroom is right in front of the room. I found that to be very convenient.
Ahmet and his wife were nice to me and I felt very comfortable at their place.
I didn't use the kitchen during my stay so I couldn't comment on it.
It is a 5-10 minute walk from the subway station and then it's about 20 minutes to Grand Central.
I would stay there again and would recommend the place.
