We booked the airbnb on the day of arrival in Athens. They picked us up at the nearby metro stop and drove us to the flat, showed us through and recommended nearby restaurants and explained how to get around. The flat is just two metro stops from the centre of the city, so very practical and affordable (a 24 hour metro ticket is approx 5 euros). The flat is simple but practical, it’s clean, there is a kitchen available and tiny balcony. All in all a great place to stay :)
