I have been in several airbnb's around Athens and I have to say that this one is by far the best experience I have ever had - wonderfully decorated, comfortable furniture, big kitchen, nice shower, sofa, double (if not queen size) bed, super sunny. It truly feels like being at home.
The location is one of the best - right next to the Kallimarmaro, the Acropolis and Syntagma Sq are just a 10-minute walk, but at the same time is in a super quiet and safe street in a buzzing neighbourhood, famous among Athenians for its bars and restaurants.
Not to be missed: the amazing view from the roof terrace of the building with one of the best sunsets over the Acropolis and the Lycabettus Hill.
In terms of accessibility, the building has an elevator inside, but there are stairs to reach the entrance of the building.
