We had a wonderful time in Instanbul and we owe a lot to Oya and Ned for that!
At our arrival we found the house easily thanks to Oya's indications. She and her husband, Ned, welcomed us with open arms. The house is as described on the website, very clean cosy, with tipical turkish decorations. Oya and Ned bought fresh and local products for our breakfast.They were very reachable (they live next door).
They were both absolutely great, they gave us a lot of useful tips (what to visit, where to eat, where to do some shopping). They accompanied us twice in town, the first time at our arrival to show us the neighborhood, and the second time to the spice bazaar in Eminönü (Oya even bargained prices with the merchants for us and showed us the secret recipe to make the perfect turkish coffee).
The house is situated in a calm street, on a hill, at 10 min walk from Istiklal caddesi (a large and famous avenue that connects Taksim square to Galata tower).There are a lot of tipical restaurants in that area.
In one word: we totally recommend Oya and Ned's house and we will gladly come back in order to continue the exploration of their beautiful city.
