I would call it a very decent value for money. The dorm I slept in (8 beds) was pretty minimalistic but nothing missing and the bed was comfy. The shower and a miniature wc room have non-see through glass doors, a bit strange kind of feeling when it comes to privacy. The morning cleaning didn't happen before the check-out time, naturally, so the wc was ..well, like when 8 guys use it a couple of times and many of them without too much consideration for others. However, it tells more about the guests than the facility itself, to be fair. There's only so much the staff can do.
Speaking of staff, they were very friendly and helpful. Not an easy job to run a place like this in downtown Athens, I guess.
The rooftop terrace view fully lived up to the hype, a truly great spot!
Parking my motorcycle required some thought, patience, and a bit of luck but eventually all was fine.
Location is great during the day: a very good gyros place right across the street, a decent cup coffee a block away. Not more than 20 minutes of a lazy pace walk to Acropolis.
The location at night... well, depends on how you can sleep with an ever present street noise coming through the windows. I wouldn't take points away here, it's what you're signing up for when deciding to spend the night in this neighborhood.
Overall, if you don't want to spend more than just over a tenner to sleep in the comfort of a bed that is a stone throw away from Acropolis, and to enjoy the evening takeaway/morning coffee with a view to remember, this place as as fine as it gets.
