The Tyr room at Ander's place is very well located to explore Oslo (just 5 mins walk from Nationaltheatret station). It is one of many rooms in a huge apartment with shared bathrooms and toilets that are all super modern and maintained excellently. The check-in was also completely self-managed with number codes and wireless fobs – which meant that I could arrive and check-in really late (1am!).
The room faces the courtyard and the only problem I had was the noise from the neighbour's (next compound) birds (sounded like ducks or geese). They were very loud early morning around 4am and sometimes during the night and managed to wake me up even though I am usually a sound sleeper. I couldn't always close the window since it was warmish during my stay and perhaps wouldn't be a problem during other seasons. This is the only reason I'm giving 4 stars instead of 5.
