This was the best Airbnb I've ever stayed in! Kumiko was extremely welcoming and made us feel at home immediately. The room was clean, extremely comfortable, and quiet. Kumiko also provided us with local tips and offered us tea and other bits and pieces which was a lovely surprise.
The location was also great, just a couple minutes from a metro meaning the city center was a 10 minute ride away. Would wholeheartedly recommend to anyone looking to stay in Oslo!
