Just book it.
This is a fabulous apartment, the most well equipped Airbnb I've stayed in. The owner, Sinan has thought of everything. Sinans' communication was also excellent and always responded immediately to any questions. Its brilliantly located, and so easy to find. We bought Metro cards from the vending machine at the airport and were there in no time.
Thanks again Sinan for the bottle of wine and late check out.
