The apartment looks exactly like the photos, it's very nice! The kitchen is fully equipped. It's quite close to Victoria station and you can find bakeries, pharmacies, local fast food and other shops. It's close to the national archeological museum (you should visit it), and taking the subway, in few minutes you are in Monastiraki.
Nestor is a great host, we didn't meet him, anyway he asked daily how our staying was going and if we needed something.
