Firstly, I must say that Gönül is a wonderful person and she really helped us a lot with some personal stuff. She is also very hospitable and would always offer us to try some of her cooking (that is delicious by the way!). Speaking of the apartment itself: everything matches with the description. You have your own, totally isolated area on the second floor with private bathroom. So it's actually more like you rent the whole mini apartment, rather than just a room! The bonus is - a large, magnificent terrace that you have access to. Overall - great experience and money well-spent.
P.S. Make sure you don't mind inward smoking too much as this is the case with this apartment ;)
