Positives:
It is located between Monastiraki and Syntagma Square with the added benefit of being central and incredibly and blissfully quiet at night. Great rain shower.
Exceptional host, friendly and patient and on call even for late check-in. This is an invaluable asset and utterly worth mentioning and championing.
Central, central, central!
Points for Improvement:
overlong check-in instructions - simplify and bullet point
Not luxury (as per description)
cement floors - no rug to pick up the chill in winter months - it was suggested I use extra towels by an elderly man who worked there.
Bad drainage in the bathroom
Not enough hangers in the wardrobe
Semi-private = 5 individual self-contained studios with PF, sharing one wi-fi and resembles more like a university dorm floor with thin walls.
The sharing of the WIFI is problematic as company servers rarely allow remote login from a server that is not private.
Pincode to access the floor of the dorm every time became irksome.
