Increadibly good location In majorstuen. Communications are good, but it's walking distance anywhere within central Oslo anyway. Frogner park is just around the corner and grocery just around the building.
The host, Kumiko, is a very outgoing and kind host. I'm not a writer, but I only have kind words to say. I really enjoyed my stay and the talks we had. It made my stay, during Covid times, so much better. She is a very hospitable person.
