Stayed at the Frogner House - Vika for 2 nights earlier this month. The unit was very nice - clean and spacious. Property is close to everything - dining, shopping, attractions etc. We were on the 6th floor and it was so quiet, even when we had our windows open overnight (to let cool air in as there is no a/c). Quick call to the staff for a question was answered promptly. Love our stay here and we’re sure to consider the FH-Vika again when we return to Oslo!
