Attached to the charming reception area and restaurant, the main building is comprised of 26 recently renovated double guestrooms and three single rooms, all with splendid views of the valley or courtyard, and many with private terraces to enjoy the fresh mountain air. All guestrooms at Fossheim are non-smoking and equipped with televisions, wireless Internet access, and DUX mattresses.

Named after being built to satisfy a rush of American visitors in the 1950s, the Amerika annex offers eight double and eight single guestrooms, all with private baths and views of the river toward Skjak or the courtyard.

Available for an intimate and charming experience for up to five guests, the original log cabins include a private bath, kitchen, and breakfast.
