Good location almost exactly between Parnormou and Ampelokipi Metro stations. A single metro train from the airport 40mins, makes it very convenient. This area is dominated by working local people, but only a few stops to Syntagma and the chaos of the center. Lots of good restaurants, markets, pharmacies, within 5 minutes of front door.
Everything in the flat was satisfactory, nothing fancy nor excessively comfortable (except the remodeled bathroom, which is great). The balcony is small and overlooks a rather busy 1 way street. The kitchen is workable, with basics for making coffee/tea.
