Oya, Ned and their daughter Julia are wonderful! They welcomed us warmly and helped us in every possible way. Their house is located in Beyoglu, in the old Pera district, and is a beatifully restored old Greek house. We immediately felt at home there and very much enjoyed our stay in Istanbul. Oya even offered to take us on a tour through the neighbourhood. We kindly accepted and went to the local farmer's market with her on Sunday where we bought lots of food (olive oil) and had breakfast (yummy Gözleme, with tea, olives, butter, honey). We definitey recommend staying at Oya's place!
