The Apartment is - as indicated - in a very central place in Yeniköy. I enjoyed very much to sit on the balcony and look at the Bosphorus and to drink a beer in the cafe just under the balcony.
Nilgun was very helpful and friendly for the arrival, to find the place (which is quite easy) and for recommendations what to do, where to eat and so on in Yeniköy and around.
Thanks a lot to Nilgun, I spent a wonderful weekend in Yeniköy.
