Hello, my name is Fernando, I'm going to be in Athens on July 3rd. I'll be staying at a hotel very close to Omonia square. The problem is that my flight will arrive in Athens around 1:00 AM, and I've heard that the area around Omonia square is a bit dangerous to be walking alone at such a late hour (I'll be there alone). I'll have to take the express bus that goes from the Airport to Syntagma square and then walk all the way to the hotel. Do you think it's safe? Should I be worried?
