The Auberge is located in the middle of a vineyard, though it is not attached or affiliated with a working winery. In spite of some language problems, the service at the hotel was excellent, and the rooms and facility were very clean. The views of the Andes were spectacular.
I would have given the hotel a 5-star rating; however, the facility is getting tired, with a lot of paint patches, chipped countertops, outdated power outlets, and some furniture that has seen better days. The office chair in our room (as an example) had no support for the seat, and I worried about falling through.
The service was great, but language was an issue, with the front desk not always able to communicate, and issues with orders being understood in the restaurant. The food was excellent if you actually got it.
Considering that this hotel is really located in the middle of a field, and that it is far from any cities in a very rural area, these are minor inconveniences.
Also, it is important to note that the hotel is about 1.5 hours from Mendoza, and down a long series of unimproved roads. Allow a lot of time traveling to and from the hotel to pretty much anywhere.
