My family of three will be traveling to the fjord area of Norway by car in a few days and will be staying in self catering cabins. Does anyone have a good idea of where to by inexpensive (by Norwegian standards!) sheets and towels near the airport? About how much will one sheet set cost? Ikea is too far north and out of my way. I realize I can rent bed linens at the cabins but want to see what my other options are. Thank you!
