Karim will welcome you with a lot of joy and a big smile ! He'll prepare all you need before you come : towels, wi-fi, beds carefully ! Even the breakfast ;) he'll make you feel very comfortable! His place is really near the center, around 15 or 20 minutes walking.
I'm sad we didn t last longer in Oslo to see him more ! I think we can say that we didn t just meet an Airbnb member, we met a friend ! Welcome to France anytime ;)
