Omonia Square (Plateia Omonias) is the center of Athens, and is composed of the actual square together with the surrounding streets, open areas and assemblage of grand buildings that include banks and offices. The neighboring area of Exarcheia (Εξάρχεια) to the north, dominated by the Athens Polytechnic and its famous band of anarchists, is a bohemian district with lots of bars and clubs visited by students, intellectuals and people who are into alternative culture.
Omonia is the exact opposite of its neighbours Plaka & Monastiraki as there is no classical attraction in this multi-cultural area, however it's where you go for cheap eateries, exotic imported goods and food and basically day-to-day items at affordable price.
Omonia Square is an important transport hub, especially for buses.
Omonia is served by Line 1 going from Kifissia to the port of Pireaus, as well as Line 2.
Adjacent to the Omonoia Square is a taxi waiting area. Taxis line up and work on "first comes, first goes" basis,
The only true great attraction of Omonia is the National Archaeological Museum in its traditional sense but the area near Omonoia is buzzing with life. A mixture of all cultures can be found there.
Near the square are a nunber of small flea markets, and some nice small streets with restaurants and cafes.

- National Archaeological Museum of Athens  - This is the largest and most popular of Athens' many museums, and is usually very crowded. Its vast collection includes treasures unearthed from Mycenae by Heinrich Schliemann; a staggering array of sculpture including the earliest known Greek figurines dating from around 2,000 BC; frescoes from the volcanic island of Santorini; as well as remains of Antikythera mechanism, the oldest known mechanical computer; and so much more that it is recommended visitors make several visits to absorb it all. To get here by metro, it is better to use the Victoria Station (one station north of Omonia Station) and walk down 28th October Street.
Omonia neighborhood is full of curious shops!
Beware of an annoying fact: there is only one ATM on Omonia square, in the metro station, and belonging to the National Bank and its interface is only displayed in Greek.
- Asian shops: from Monastiraki, just walk down Athinas street. On side streets such as Evripidou and Sofokleous, you'll see many Chinese, Arabic or South-Asian shops which are interesting for spices and basically all kind of imported goods that are inexistent or quite expensive in Greek shops. Beware people are usually not fluent in English.

LAN outlet is in every room--but not supported, according to reception (and not tried). Single €60, double €80 (breakfast included).

As a visitor, you may be encouraged by Athenian people to avoid Omonia area especially at night, however the neighbourhood is intensively patrolled by fully equipped anti-riot units, or at least on major intersections.
Omonia is notorious for pickpockets and prostitutes, so keep an eye on your belongings.
There are many people who use drugs in the open even during the day and can be a harrowing sight for those not used to it. It is strongly advised not to bring children here for too long. Particular places to avoid are roads right of the National Archaeological Museum and the south end of 3 September St.
More recently, Sofokleous St (a major street south of Omonia), especially the western part near Pireos St, has gotten a reputation for crime and drugs.
