Julian is a great host. He is quick in his replies and is willing to help you discover Oslo. More importantly, he has a great apartment. The apartment is very well equipped with a good kitchen, a big tv, a proper audio set and even tabletennis!
You almost don't need to get out of the apartment. But you definitely should! The apartment is well located in a very active neighborhood of Oslo. Many restaurants, bars and coffee shops right around the corner. At the same time, there is no noise pollution in the apartment itself because it is off the main street.
Recommended to anyone to day here!
