Omonia is the epicenter of Athens, its beating heart, a stupid and ugly square that sees all social classes and all types of people passing, business man, tourists, junky, clerks, students, prostitutes...
If you pay a little attention to what happens around this square you will learn a lot about the situation in Greece.
There are many hotels around the square and adjacent streets, some hotels are brothels, many tourists complain about the quite creepy atmosphere of the neighborhood at night.
