This was our first airbnb experience, and I must say it has now set our expectations very high from other airbnb's. The apartment is lovely, well maintained and matches the pics in the listing. Also, really close to the city centre, at a 10 minute walk to the Acropolis and 15-20 mins to syntagma square.
Also, before going, we were concerned about the guests in the other room and general safety, but our neighbours turned out to be really good people and we had fun interacting with them.
