Stayed for a week, alone. Very small but fully equipped studio with a proper bathroom and a big bed. Good and very central location, even though you need to use the bus/tram to get to the next subway. It's been a while since the apartment was last renovated, but that's only relevant in comparison with the Norwegian standard of very frequent modernisations. The owner was very quick responding and forthcoming. Suited my needs for a business trip well, would come back.
