Dimitri was very responsive and let us leave our bags before check-in which we appreciated! Perfect location for sightseeing, was 10-15 mins from great little restaurants and cafes in Psyri and also from the Ancient Agora! The furthest walk (to see historical ruins) was to the Temple of Olympian Zeus (30 mins).
The layout and amenities are good, and there is even a nespresso machine+pods (free) and cold drinks in the fridge (1€/can).
The street noise of cars passing can be a bit loud at night so if you are a light sleeper, just bring earplugs. The streets nearby are a bit dark and empty but I never felt unsafe.
