First of all lets say the only reason you should be in Borgarnes is that you are on your way to somewhere else. That said th hotel was very clean and comfortable with the feel of an american business hotel. There is an excellent hot tub on each end of the hotel, perfect for unwinding after a day of hiking in nearby Thingvellir. There is an onsite restaurant as well as a couple of options in town. We did not eat at the hotel so i cannot comment on the quality, though it looked quite nice.
An added bonus, the views of the mountains from the back of the hotel are excellent.
