Amazing terrass! Bus 025, 026 and 027 stops right outside the building, which are easily accessible from Syntagma. One street down you take the bus going to Monastiraki and Plaka. Subway to the airport is about 1km walk, which really isn't that far. Me and my friend really recommend this place! Supermarket both small and big are really close by, 10 meters or so. We enjoyed the terrass so much and spent quite some time out there. Very nice and contemporary apartment!
