Ups: 24 hour reception, easy check-in/check-out, speedy elevator, public transport very close by, great personnel, mini-market close by, no-noise fridge in the room, clean bed and sheets and lots of towels, heating.
Downs: My earplugs came in handy as my room faced the street, there was a problem with my key card - had it reset at the reception, it was easy to see that the interior was not new.
Conclusion: Given the low price in early December and being a solo traveller, this was a very good deal, and I would be happy to come back.
