I arrived a bit earlier than the check in time, and Oytun was happy to accommodate me. The room is a bit small, but extremely clean and cozy. Few minutes walk to Taksim Square and Isteklal Street, metro and bus station (change 2 buses to SultanAhmet). There is always some one at the reception 24 hours, and Oytun and his colleagues are extremely helpful, if you need help in planning a trip or need advice. They even let you borrow the metro/bus card - just load money to use it, and return once done. They can arrange shuttle/taxi to the airport. Taxi charged me 55 TL compared to Uber 100 TL. Rooms can be a bit noisy at night over the weekend, but nothing unbearable. Will highly recommend people to stay here.
