Great quality for the price
The place is very clean as it is constantly cleaned by professionnals, the room contains everything you need: a bed and a table, the common places for toilet and shower are rudilental, but it seems to be a normal thing in greece, and its not a problem at all (I used both), there are 2 for like 4 or 5 rooms, so it's usually available when you need it
I did not used the common living place that much as I only needed a place to sleep, the view is breathetaking, and the place around is immersive as it is the Athens market
Something that should be mentioned: the outside can be a bit noisy if you let windows open (as I have earing deficiency I didn't care that much)
If you are looking for a place to sleep, you will have whatever you need, and the price is one of the cheapest you will ever find for a room, even in Athens
