Ee had some problems to find the entrance of the building. We called Martin and he came down to show us the way. He gave us a map of Oslo and answerd us all our questions. We saw a metro station 5 Min away from the building, but we never used it.
The room is nice and exactly like on the photos. Everything is clean, shower and kitchen we had to share with the host family and (i think) 4 other guests.
We had to print the boardingpass for our flight back home. Martin helped us imediately and printed us the documents.
When we come back to Oslo one day, we would stay there again, it was a great time and perfect to explore the city!
