We stayed in Athens for 4 days and the best thing about this apartment is it's location. Everything major tourist attraction is within walking distance , and the streets outside are very tourist-friendly, there's a great party-vibe at night, and the restaurants/pubs outside are probably one of the best in the Athens city center.
The host is very kind, honest, and very quick to reply to any questions/queries regarding the apartment or Athens in general.
All in all, positive experience, 5/5 stars, would definitely stay there in the future if we visit Athens.
