Arne was a welcoming, friendly, and responsive host. His apartment is beautiful, modern, clean, and very cosy with the fireplace. It is also close enough to use public transport to easily get to all of Oslo. Our only slight complaint was the bed was uncomfortable due to it just being lots of mattresses on top of each other instead of a bed frame. It is also worth noting the apartment is on the top floor with no lift access so be prepared for that, but it's well worth it in my opinion. Highly recommended and we would stay again.
