I really appreciate Nihats responsiveness and awareness of Istanbul. The room is as expected, cosy and on the 4th floor of a building without elevators. My estimate is that it was no bigger than ~8 sq feet (~2.6 sq meters) in size. Nihat kindly helped me carry one bag upstairs at early check in. Location in Taqsim Sq was very convenient. He is a gracious host and offered use of umbrellas when raining. Street facing room is mostly quiet at night.
