The hotel was nice overall, but I would not classify it as 5-star. Then again we paid less than 150 USD, so that is OK.
It is up in am mountain, with a good view of Ushuaia bay.
Big room, good bed, good spa and pool, excellent breakfast.
Service was patchy (had to ask them 3 times to make the safe work) there was no tea/coffee in the room, and unlike stated in hotels.com, no airport-hotel shuttle. Taxi ride cost about 120 pesos to the airport. They do have a shuttle into town, 4-5 times a day.
