Trude's place is lovely,it was cold when we were there but there was heating and it was comfortable. If you like harder beds,use the sofa,if very soft,bedroom bed is good for you.
We never met Trude even though I believe she was around in their part of the house,but on the other hand I know she would help if we needed things. We did not need to ask much as we were visiting a friend who lives in Oslo.
