My boyfriend and I only stayed in Sokols room for one night - arriving late from af greek island and leaving for the airport next day. The room works for that purpose.
I've stayed other places in Athens where I got more value for money - but the room got what you basically need. Clean room, check in works, good communication and all that jazz.
We were awakened at 7am by a lot of noise. I think someone is renovating rooms in the building - but I suppose that's not at permanent thing. Until then it was nice and quite to sleep in the room.
