Excellent location. Very central to access everything in Athens. Great value for money. We initially had a few issues with cleanliness in the bathroom and living room, but Vicky's team (Georgia and Panos) went over and above to resolve our concerns. They set up a cleaning lady within a few hours of our comments, and had them take care of any minor issues we had.
Also, we arrived into Athens at 2am due to flight delays (terrible time to arrive as there are no trains running at this time). Yes Georgia stayed awake and ensure that our driver (Panos) stuck around to pick us up at our new flight time. He brought us safe and sound to our apartment.
Overall -- what we liked was the apartment's location, the view of the Acropolis from the living room, and the excellent service from Vicky's team. What may be moderate is the entrance to the building and the old, dingy elevator that takes to your room --- BUT HONESTLY, for this price, you are getting fantastic value for money. Overall, highly recommend this place.
