Actually almost every common place was pretty cleaned and well maintaned.
Reseptionts are extremely kind (I experienced very polite service and saw how they gently treat other guests).
Hotel has separate luggage room, sparated bath- and toilet-rooms, chiling zone equiped with coaches and pillows. A lot of wooden boards, chairs and even el-scooters (available for rent y city apps) stays outside.
Tip: check availbility here via different apps and you can of the chepest price for overnighting in Oslo.
Some guests don't care about their used bedding, people leave a room leaving garbage and some stuff inside. Ppl dont care about silence, so you can experience door slaming in the room, but ofc it depends.
Nothing critical.
Seems like it would be helpful to put a list of the rules on a door in the room og maybe reception staff can remind.
