Sergio was easily the best air bnb host we have had to date. We arrived earlier than we first said but this wasn't a problem and Sergio met us promptly with the keys. He showed us around and even bought us water and a welcome gift. He then gave us advice about where to go and what to do in Oslo. Check out was just as easy and the apartment is perfect for a couple. It's bigger than the pictures suggest and has a well equipped kitchen. The centre is easily accessible via tram. Could not recommend highly enough!
