Translation of whistling in Spanish

We agreed to stay in the room with no windows and unpacked our bags. We wanted to have dinner and went out to a Sushi restaurant a friend told us about. It was a great place with great atmosphere.
The memorial consisted of a small museum and monument which was displaying skulls of civil war victims. It was sad, brutal and scary. It is certainly not the place were you would take tourist on day one.
Anyway, our stay in Puerto Varas was nothing special, as the weather was terrible. We continued to Bariloche the same day. It was a 6 hour long bus ride passing the Andes mountains. The views were amazing.
