Really excellent. Lovely view of the Acropolis from the sitting room, two of the bedrooms & the terrace (where we ate breakfast), beautifully presented and well-equipped apartment. We loved it.
As was flagged, the ground floor entrance is on a busy street and nothing special, but perhaps because of that, when you go up to the apartment, it's even more stunning.
Also really near the temple of Olympian Zeus and a useful supermarket around the corner.
