Perfect place to stay for a couple or solo traveler for a few nights. I've been to Athens a few times and this was by far the most centrally located accommodation I've been in. Amazing access to Plaka, the Acropolis and amazing bars and restaurants.
From the Athens airport you can take the M3 metro (train) straight to the Monastiraki station and the Airbnb is only a 4 min walk from there.
Easy self check in and luggage storage as well. I'd be glad to come back. :)
