Thank you dear Engin for your hospitality. You are the best host we have ever met. He carried our luggage to the third floor when we checked in, and carried them again when we checked out. He answered for all questions , predicted what we wanted. We forgot some stuff in his apartment, and he said that he can send it by mail to our next point of destination in Turkey. We were in Istanbul for the first time, and thanks to people like Engin, we want to come back again and again.
