The good first: the apartment is beautiful. It's tastefully decorated, in a wonderful location, and has comfortable beds and furniture. The hosts are very quick with communication, and my family had a really lovely Christmas and New Year's at the apartment. However, it was dirty when we arrived, and we had to do a lot of cleaning ourselves before we could relax. I think that if the hosts bring in professional cleaners in between guests, this will be one of the nicest AirBnBs in Oslo.
