I don't expect anything luxurious in the middle of a desert in Bolivia, but I was disappointed with this hotel because it didn't live up to what was advertised. There didn't really seem to be much heat on at all even though this was one of the main selling points of the hotel, which made for an extremely cold stay. The only thing that worked as promised was the hot water shower. The electric blanket was also very welcome, though the fact that electricity (not just heat) was turned off at night meant that nighttime was also quite cold, although I have to say that the blankets themselves were pretty warm and I didn't feel cold while sleeping. Compared to the other hotel I stayed at on the 3 day Salar de Uyuni tour, this hotel was rather disappointing. Although I recognize that the hotel is essentially run by one family, I expected the hotel to at least live up to what it promised (heat!). The food was edible, though it was cold. The service wasn't terrible or anything, but I have to say that the family running the hotel didn't seem interested in addressing any of our concerns.
Even keeping in mind the location and the standards of living in this part of Bolivia, this hotel was a disappointment.
