Please note
The original architecture and design of the Monasterio has not been significantly altered,
 and thus the rooms reflect their origins as a home for Jesuit seminarians.
There are no two alike and  they all vary in size and format.  

Hotel Monasterio - Oxygen Enrichment
Up to 60 rooms with oxygen running simultaneously; 4 sets of connecting rooms.
Oxygen is piped into the rooms 24 hours a day, oxygenating the rooms down to an atmospheric pressure of app 2,400 metres which is low enough to prevent ill effects from altitude sickness.
