This the recommended hotel for WEF Iceland as it is most convenient; being located just across the conference venue so that you can simply walk the distance. We suggest that you make your hotel booking as early as possible, preferably before 10 September as room availability is limited. Most delegates and speakers will be staying here, so the vibe and ambience will be very vibrant.
You can book directly with the hotel quoting WEF Iceland.
