Cruz Loma Hotel.

The professor and department chair of our department stays here every other summer before he heads out to the Andes for field research. I book it for him every time -- he loves it here!

We stayed at Sierra Madre for one night. The room was a good size and had a large balcony. However when speaking to friends it was overpriced compared to other rooms in the city. That said, the staff were friendly and the breakfast good.
