I was in Narvik for a conference. We prefer staying in local apartments rather than the conference hotels. Just gives a better feel for the community.
Apartment was as described: clean, compact, near the center of Narvik and close to the University.
I rented the apartment over a year before our stay and communication was always prompt and helpful. A bit of latency trouble with the VRBO app near check-in so Anders thoughtfully called to confirm check-in went OK.
This was a ground floor unit in a building that is a little bit older. Internet was very good.
Overall, the unit served us well.
