Torbjørn is a wonderful, friendly, easy-going guy with a fantastic flat in barcode! Barcode is one of the best areas of Oslo to stay, even in winter. You're situated right next to the architectural wonder of the DeLoitte Building, which has impressive geometric design. There is access to a very cool terrase on the 9th floor (which is where the flat resides, access is just down the hall).
The flat is warm, cozy, full of hygge if you grab a few candles. The space is quiet, well-built, and well laid out. The bed is one of the best we've ever slept in, a type of memory foam that provides incredible deep sleep! Shower includes a rain shower and the pressure is so fantastic. Great access to big sights like the Opera House, Promenade, Sentrum (everything in Oslo can be reached quickly). A quick walk over one of the bridges gets you to the cultural center of Oslo, Grønland, and offers some great deals on food and grocery.
We stayed here for a month while relocating from the USA to Norway for a new job and found it to be an excellent stay.
