We have searched Internet for information on self serve laundromat in Bergen Norway. Do they have any
Did you try a search using the Norwegian word " vaskeri " - you'll have to run the responses through a translator.
I googled "laundromats Bergen Norway" and got several responses. One of them was a Trip Advisor response that listed the address of one. So maybe you could post your question on TA if you can't find the answers on the internet by googling. Another suggestion would be to post this question on the "To the North" section here.
Go to this site: http://www.yelp.com/search?cflt=drycleaninglaundry&find_loc=Bergen address number 3 on this list: Lille Øvregaten 17 is near the funicular and I believe is the one listed in Rick's Scandinavia guidebook. Also, you might want to check with your hotel/hostel...they may have laundry services available. Elaine, good luck in your travels!
