The place is correct. A bit far from the center but well served by public transportation.
Problem was communication with the host. Despite using our own sleeping beg, the host wanted to charge us for using the bed and matras an extra 500 SEK.
Generally, Kersten was more occupied with having us well behind the room, respecting the many rules and not bothering her than just being nice or welcoming. This is the first time ever I wrote it on airbnb. I never thought I would.
