Sertac was very helpful host. It started from his advise on the mean of transport from the airport and ended with the lab to take the PCR. If you need anything don't hesitate and just ask him. The location is perfect, close to Taskim Square and Istiklal Street yet it's quite. Also, the room is big and would easily fit two persons. I really liked the local cafe and tea places close to the room. Overall, it was of a good value for me 👌
