first of all, Khadijeh is a great person, due to change in my plans I had to alter my reservation and she was so understanding and helpful. the house is very close to nice cafe's and restaurants and also lively nightlife of Istanbul. Dulmabahçe and Yıldız palace are in walking distance and you can easily go the Asian side or the islands from Beşiktaş pier. my stay was quite short but it was lovely experience.
