I was in OSLO 2 days for work and The hosts Axel and Bjorn where perfect even though they were travelling when I stayed there for 2 days they made sure I had a key maps with tram lines and gave me recommendations for restaurants to eat.
the apartment was impeccably clean and bed comfortable and the are quiet and relaxing
The amazing view at night was so relaxing from the terrace and the artsy decoration was totally to my taste (I'm a designer) and the modern art museum/ center of town walking distance
