It is my second time staying at Oya's place, and as the first one everything went well. Oya's and her husband are very welcoming and helpful in everything you need to stay comfortable at their house and in general in Istanbul. The house is cozy and full furnished and equipped with all you need for a good stay in Istanbul. The neighborhood is a nice one and I never felt unsafe. Also It is very close to Taksim and to place where you can get public trasportation to get around and visit Istanbul. The hood also makes you to breathe the real Instabul more than other turistic place you may go visiting.
I recommend Oya and her house to everyone visiting this great city.
