We stayed there with my partner for a night, arriving by train from Oslo, and leaving next day by ferry to see the fjords. So we wanted a convenient spot to explore Flam and its surrounding easily, there isn't much in Flam, and there isn't anything cheap... This place is very clean as other reviews already said, and I can confirm that the bedroom is ridiculously small compared to the size of the open plan living room. The beds are also tiny, and a twin (although I had requested a double). The owner is polite, and that is it, don't expect a map of the town or any explanation of any sort. Also, there is no coffee, no tea waiting for you when you get there, so be prepared. That being said, there's a small supermarket 100m away, and the kitchen is very well equipped. It's also probably the biggest TV screen I've every seen!
If you stay longer than a few days, you probably want a car there to explore, otherwise great place to be in Flam.
