Only good things to say! Mari was nice the place was perfect for what I wanted (clean, comfortable etc - nice balcony to sit on as they sun goes down). Other reviews talk about how easily it is to get to the centre via tram or bus but the river walk is the best way by miles. You can even leave the river at Grünerløkka (10/15 mins) where are great places to eat and drink etc (arguably better than the central tourist places). So thumbs up...
