Location: Exarchia is very cool alternative district, full of small shops, cafes, bars. The flat is next to a hill, from where you can enjoy the sunset with Acropolis view.
Accomodation: It's huge and I like the style. If I could, I'd move there, even though the colour of the kitchen is quite unusual ;)
Communication: It was well organised and friendly. We had a warm welcome with a lot of tips and recommendation.
Conclusion: perfect
