Although I have stayed for a month but did not have a chance to meet Vegard.
The communication was just ok. Check-in was easy but No proper cleaning practices are provided. Although I did my best however still they have concern on it. Maybe further guidance can be provided in terms of cleanliness as its quite subjective thing.
It's a good place to stay in Oslo, very close to the opera house and barcode building. The apartment is good for a single traveler but make sure you are aware of proper deep cleaning practices.
