Emma's place is in a perfect location for everybody working or studying at UiO Campus Blindern (less than 10' walk!). The airport shuttle bus also stops almost right in front of her door which was very convenient. Just be aware that you need to walk up quite some stairs since there is no lift.
Self check-in is super easy and Emma is reachable at any time (and responds super fast).
The room is spacious and comfortable and you are free to use the kitchen (a supermarket is just a few meters down the road).
Emma wasn't there most of the time but we met one evening and had a very nice talk!
All in all a very nice stay! I can definitely recommend staying with Emma!
