We had a great time in Oslo, Cathrine was a perfect and great host, she has been waiting for us till late night, showing us the apartment and leaving us several tips. She was easy to communicate with and always answered quickly with many suggestions! The apartment is very well located and close to public transport (there's one tram every 2-5 min), in 7 minutes you're downtown! Great place to stay and perfect start to sightseeing the city!
