Would definitely stay again!
Pros
-Very clean
-Fast wifi (I was able to have clear zoom calls only by the couch and bedroom, the desk doesn’t have strong wifi)
-Kitchen has everything you need
-5 min walk to the train and 25 minutes to the center of Oslo
-lots of grocery and convenience stores nearby
-felt very safe as a solo traveler
Things to consider
-the bed is comfy but the pillows are really hard so maybe bring your own pillow
