The best of a hotel (great bed, internet, Space, bathroom, clean) & the best of Airbnb (location, host communication, looks like the pictures)
Things to consider:
If you want to storage your loggage for some extra time in Athens, you won’t be able to leave it at the Airbnb. But Georgia recommend us a very close loggage storage.
Also there is a very nice restaurant in front to have a drink or breakfast.
