We were 4 people that traveled to Athens for the new year, the apartment is new and clean, with 2 bedrooms, a kitchen, and a toilet (same as the Airbnb images).
The host was responsive, helpful, and informative, he even tried to find a tavern or bar for new year's eve, communication was great and fast, and he provided us with all the information we needed for this trip.
We arrived late and the check-in was not a problem, the host greeted us and explained everything we need.
I highly recommend this apartment and the host if you want the best experience in Athens.
