Costa's parents thankfully waited for us to check in after our ferry was delayed. They gave a great introduction to the place and left us with a great breakfast. The place itself is very well furnished and with cool board games, books and DVDs. Bed is the comfiest I've slept on during the trip. The neighborhood is lively with lots of cafes pubs and restaurants all within a few minutes walk and with interesting graffiti everywhere you look. Exarchia has an anarchic feel but without being seedy. Would stay here again next time I visit Athens.
