Pom & Tom are great hosts. They're interesting to talk with, offer interesting suggestions and make you feel at home.
This was my first time sharing an Airbnb and it felt great. I'd definitely come back.
Thanks to them, among other things, I found out about "The Well" Spa which was a wonderful experience.

The place is very nice, great WIFI, the kitchen and bathroom are really well decorated and cozy.
The location is beautiful, quite close to the river and there's a REMA 1000 very close by where you can do your grocery shopping.

Tips to keep in mind:
Remember it's in a 4th floor so make sure you account for that.
The washer is in the building in the ground floor.
The table was long but narrow (Just enough space for a big notebook). The computer chair was comfortable. You can see it on the picture.
The airbnb has 2 rooms for guests so you might share the spaces with others. It's on the listing but it's good to be aware of it.
During my stay, I only shared 2/3 days with other guests and it was completely unobtrusive and pleasant.

I really recommend this place and the hosts. Enjoy your time in Oslo!
