Positives first: it's in a really good location 5 minutes walk from Sentralstation, I got 2 good nights sleep there even though on a major road (my friends in Comfort Hotel by the station got none as the stations square is noisy at night with drunks etc kicking off). The staff were helpful, it was cheap by Oslo standards and they stored my luggage for me before I went to catch an airport train. Beds comfy, decent shower.
Breakfast a little basic but acceptable, a ham/cheese sandwich, pear/apple and some apple juice.
Cons: the toilet clearly wasn't cleaned properly (some brown left around the outside rim), ketchup (I hope) on bedside table when we arrived. Also, it wasn't obvious to me, and wasn't mentioned, that there was a coffee machine hidden in the lobby until I was leaving, so I spent money across the road on the coffee shop.
Overall, not a bad place to be.More
