I popped into Pirwa Posada one night to see if they had a single room available in a few days' time. When I managed to get my point across in broken Spanish and asked to see a room, the receptionist didn't seem too eager to help.
When I checked in to my room a few days later, I realized there was no hot water. The room smelled of pungent cleaner.
The mattress dipped in the middle, which made for a bad night's sleep.
With regards to security, Pirwa Posada is definitely lacking. Photocopies of the guests' passports are left in the cubby holes at the front desk, within reach of anyone standing at the desk. Every time the receptionist left, the copies of the passports were essentially left out in the open.
The only good redeeming quality about Pirwa its its central location, though this came with an inherent drawback in that every time you step out, you are bombarded with offers of massage deals, restaurant menus, and artwork.
