There are not enough superlatives to describe our stay at Pousada Les Roches. The cabin (chalet) we stayed in was spotless and charming, the pousada grounds and setting in the Cuiaba Valley are beautiful, and the food in the restaurant was excellent. What sent our stay "over the top" (in a good way) was the service we received from Americo, the owner, and all of the staff. Everyone we encountered went well out of their way to make sure that everything was perfect for us, and it was! We spoke only very limited Portuguese, but generally this was not an issue at all as many staff speak English and those that didn't were very kind and patient with our attempts at speaking Portuguese.
One thing to be aware of is that the location is fairly remote, and activities or dining off-premises definitely requires a car. That said, you can happily spend a weekend here and not ever leave the property.
