We stayed here during our first visit to Oslo and the location is perfect. Nestled in the heart of central Oslo, it's walking distance to pretty much everything.
Communication with Elin and Joakim was great and check-in/check-out was a breeze.
The place itself is lovely - a well-appointed loft style flat with large windows. There's also a roof terrace. One note on the windows (and this did not affect our review at all) is that they do not have blinds. We visited in November so this did not affect us at all but anywhere visiting in the summer who likes to sleep in, I'd think this would be a consideration. Elin and Joakim did send us a note to that fact.
All in all, highly recommended place and we hope to get the opportunity to stay here again.
