Elsebeth's place was absolutely a highlight of our trip - the cabin is amazing, better than you'd even think. There is a nice view of Oslo from the bedroom window, and a running stream right next to the property, that you can hear snuggled in your bed at night.
One thing to note though, the place is up quite a hill - so if you have ability issues and are not able to do a long, somewhat steep climb, be prepared. You'll park a little away from the cabin, and will need to pull your luggage up. For us, it was absolutely worth it!!! And Elsebeth was a great help as well, as we arrived in the dark evening.
This place is a must! While we only stayed one night, it was great to see that it was also so close to public transit, should we have wanted to venture into the city. Would definitely stay here again.
