Myself and my partner had a very comfortable stay at Arne's place. The view from the balcony was amazing, and all the sights range from a 20min to 45min walk from the apartment which was perfect for us! The flat was lovely and bright and modern in its decor. You do have to navigate 5 flights of stairs to get the apartment so do make sure you're prepared for that as there is no lift. Arne was good at communicating and was flexible with check out which was much appreciated! Only downside for us was that the flat could have been a tad cleaner, and the kitchen could have been better equipped for cooking meals if needed. Overall we had a lovely stay in Oslo.
