This place easily is five stars. The apartment was immaculately clean, and there were ameneties and touches that were included not even advertised in the listing. Yannis and Rena were extremely helpful in providing local tips as well as an early morning taxi on late notice. I would definitely book with them again on a visit to Athens. Just bear in mind there's a flight of stairs that has to be climbed to make it into the unit, and the neighborhood is not the absolute safest, but that could be said about most of Athens.
