I stayed at Casa Suiza, for one night and never again. I was the only guest on my level and the only other guest was a nice family below me, but after returning from a surf, some of my stuff was taken from my room. I confronted the workers and they didn't care. Which confrims it was them. After I moved to a different hotel, I then found out this was a common thing, at this hotel.
The only place I had problems in Peru.
