Athanasios’ apartment lies just 5 minutes walking from the metro station. You also have bus and tram stops. There are a lot of restaurants, supermarkets, and others around the place. Olympikeion 4 minutes walking and also you can see it from the balcony; Acropolis entrance (side entrance, not the big one), 10 minutes walking. Syntagma square, 12 minutes walking. As you see, it is very well connected.
The Apartment is super. Comfortable, modern, and you reach it by elevator. The view of the city is beautiful.
Athanasios is nice and answers quickly. He always offered us help. I recommend this airbnb.
