Finding your way in the airport is quite easy, getting from terminal to terminal also. Wifi is free yet it requires you to enter your cell phone number to receive a password via SMS. I entered my number in every possible format. Never ever got the password.
This review may be a little biased due to the fact that this airport is what made me love aviation and travelling. The airport gives me nostalgia every time I visit. Great designed buildings, and from what I hear, the airport has become a lot better since the new terminals and renovations have been finished.
Beautiful airport despite old. Staff is nowadays very friendly and passport/visa control really fast! Baggage claim sometimes very slow.
