This was a very lovely stay, but I have to add that I was upgraded without realising it. Thus my review is not for the single room but the double room with a small "living room". Good and quick communication. The room (double) was one of the coolest I've stayed in when I've been in Oslo. Nice touches, such as free snacks (even from Pascal), yoga matts, tote bag and camera to borrow. Location is unbeatable. Also, the room was nice and warm, which is not a given when you stay at a hotel in Oslo.
Only issue I had was locking the door when leaving the room, which happened twice (it didnt happen automatically). The team was quick to respond to offer guidance and mainenance assistance. Highly recommend this hotel!
