The flat is not a home but rather an ex office, sketchy transformed into a studio.
One window is broken and does not close completely (making the flat very noisy), the bathroom does not have a bath curtain, resulting to wet floors and a door half rotten from moisture, and the kitchen and cutlery are old and mostly decorative.
Regarding cleanliness, it was ok I guess, but upon close inspection, all the surfaces and joins where old and damaged.
On a positive note the location is good with quick access to the city centre.
I have stayed in better places in Athens in the same price range and it would be hard for me to recommend to anyone, as it mostly looks like a make a fast buck place rather than a proper studio apartment.
