We were on holiday in Oslo for 3 nights. We stayed in Frogner apartments and we were very happy for our choice. The apartment in Arbinsgate was near everything: the museums, the metrostation and Karl Johans gate (mainstreet). Also good restaurants (e.g Aker Brygge) were near. The apartment was clean, quiet, comfortable and convenient. The staff was helpful and friendly and check in easy with the check in machine. The check out was also very convenient.
