We had a lovely stay at Per-Christian's space. I was there with my parents and boyfriend and there was loads of space for all of us. The apartment is beautifully decorated and very comfortable. The check in process was also very simple and Per-Christian was very quick at responding to messages and helping us out. The only thing I would have loved is some recommendations of nearby places to eat as Oslo is very expensive and it's nice to get a local's opinion. However we did find a lovely Italian place nearby called Roald & Umberto which I would recommend and the nearby branch of Kaffebrenneriet, a local chain I believe, was lovely and a short walk away. Overall I would definitely recommend staying at this gorgeous apartment, it really made our time in Oslo very comfortable.
