The tourist info bureau steered me to Jacob's Apartments after I stayed in an awful private apartment for one night. Jacob's was marginally better.
First night was in a 1st floor room, where I listened to stomping feet above my head and the people downstairs in the bar.
Second night I asked to be moved upstairs, and had the misfortune of being next to a screaming child, plus road noise.
No matter where you stay, you will hear everything. Don't plan on sleeping much.
Bergen is terribly expensive for being not-so-interesting. I'd recommend paying a bit more and getting into a hotel instead. At least you'll sleep.
