Our stay at Eleni's place was great!
Mike (Eleni's son) was waiting for us upon arrival with no issues.
The location is central to the centre of Athen's/Plaka district. Everything was within a 10-15 minute walk. We felt very safe in the area.
Mike was very helpful to answer any questions we had. You have access to WIFI and a local phone if needed. The apartment was also very quite. Full amenities - would be very helpful for longer stays if you want to stay in and cook.
I highly recommend this place!
