I missed my flight to Athens in the morning so I arrived quite late at night catching the next available flight. Maria (Rio's wife) greeted me and showed me around their perfectly clean, well located apartment. The neighborhood felt safe and the food at the tavern around the corner is excellent.
Maria was extremely helpful as well and helped me book a cab for my early morning ferry the next day. I would definitely like to stay at Rio's longer the next time I visit Athens :)
