Ismail is a great host. I arrived in the middle of the night, and he met me. Ask him anything, he helps you. For example, where is the best currency exchange, or he can find you early morning taxi to airport (500TRY).
Thank you!
Also if you are going to work there, notice that internet isn’t fast enough. And I didn’t expect that Istanbul’s weather isn’t warm in March.
Location is great. There are so many historical places around. For example, AyaSofia is in 200 meters.
