Spiros' place is in a nice neighborhood in Athens - we had plenty of great choices for food, coffee and drinks around the area. You could walk about 5mins to nearby bus stations (bus schedules aren't as reliable as the train), 10mins to the nearby train stations and 20mins to the Acropolis museum.
The place was clean, has a modern bathroom, a washer and a complete kitchen. The aircon worked well, and the WiFi is very reliable.
Spiros was also very kind to arrange the airport transfer as our flight arrived late at night. Nicole, his cousin, welcomed us to his home, showed us how everything worked and gave us some tips and directions around the neighborhood.
