I have stayed for one day at Dionysios' place and it was a wonderful and heartwarming experience.
Dionysios was always very thoughtful and is a really, really nice guy. The place is at an excellent location (almost next to the Delirium Cafe and very close to Brussels' main attractions), and the price is simply awesome - especially considering that talking and become friends with Dionysios and all his family has no price!
I am really happy to have met this very friendly home in Brussels.
A hot take is Dionysios' restaurant, with great food and exceptional beer!
