Athens, of all the cities I've seen, is the one I found most surprising. The mixture of East and West together with absolute chaos, makes the city of Athens a perfect place to get lost. My last two visits I stayed at Hostel Zeus on Sofokleous Street, a street that crosses Athens Street perpendicularly, which is in the center, about 3 minutes from Omonia Square, 2 to the market and 10 to Monastiraki. The hotel itself is kind of shoddy, but it's well known with interrailers so there is a great atmosphere. Also one of the people working there is cool and we hit it off. Athens Street has a lot of vitaliy and is a pleasure to walk through there.
