Derya was amazing. She checked in on me everyday and also gave me suggestions for places to eat, visit and shop. Extremely clean house, that is centrally located. Just a mins walk from Istiklal street and 4minutes walk from Taksim Square (where you have access to the metro, bus stop and hop on hop off buses). 11mins walk to the airport shuttle stop and like me, if you love walking, takes 25mins to the Dolmabache Palace and the Bosphorus. Loads of eateries around and Tourism Police all over the place. I enjoyed my stay at Istanbul and their house was very cozy.
