Konstantinos is a great host! He is extremely supprortive with all kinds of organisational and logisticall matters, if this is wanted. The apartment is a jewel in the heart of Exarchia, such a lively and interesting neighbourhood that has a lot to offer. A special recommendation is the open air cinema just opposite the building, which shows films in original language with subtitles.
The apartment is beautifully furnished (it looks even nicer in real life than the photos) and is well-equipped. My six friends and I would definitely come back and stay at the apartment again! Thanks for everything, Konstantinos!
