Fredrik (our co host) was so friendly and helpful with bunch of informations. The place is neat and clean, and most importantly close to public transportation. Only 5 min walking from National Theatre where our favourite place, the Christmast market was located. The ambience was very nice despite the rain in Oslo :(. There are bunch of good restaurants and pub nearby, even convinient store. The heater didnt work while our 3 days stay, but the apartment itself wasnt that cold. We didnt get to see the aurora borealis, but overall we love everything from Oslo. Definitely will rent from Fredrik if we get to visit Oslo next time.
