We live in Holargos, a well looked-after residential suburb with middle class population, located about 6 kilometers (northeast) away from Syntagma Square. I consider it a great place to raise your kids, socialise, shop and have fun.

What Wikipedia says

Holargos (Greek: Χολαργός) is an affluent suburb of Athens, Greece, located northeast of the city center and about 6 kilometers (3.7 miles) away from Syntagma Square. Since the 2011 local government reform it is part of the municipality Papagou-Holargos, of which it is the seat and a municipal unit. The main thoroughfare is Mesogeion Avenue, which connects Holargos with central Athens and the northern beltway Motorway 6.

Holargos was the name of a deme of ancient Attica. The most prominent citizen of ancient Holargos was Pericles. Holargos was part of the community of Chalandri until 1933, when it became a separate community. It became a municipality in 1963.
