Hasan understands the very definition of concierge. Before we were even aware of a problem, Hasan was at hand to sort it out, from arranging sim cards so we could navigate around the city with ease, to helping with airport drop offs and offering other vital amenities. A lot of these things were important, particularly within an alien country where all of these things are taxing and difficult to acquire.
Overall, this was the best service I have received from an airbnb host.
