This place is a dump, disgusting, depressing, ugly, dirty, run down.... there are not enough negative synonyms in the thesaurus to describe this pseudo guest house. The mattress was soiled, reeked of old sweat. And since they dont use fitted sheets, most probably you will wake up in the morning lying directly on top of this sticky, smelly mess. The bathroom is deplorable. The shower drain sits outside the shower area! Water runs through a hole in the base towards the bathroom floor drain. I never bothered to get breakfast, since the area where they serve it is repugnant. The last night the water heater broke so I had to shower with cold water, and the temperature outside was in the low 60's. Mendoza is high in the pre-Andes, so weather is pretty cold year round. The only non negative thing I can say about this dump is that it has a fairly good location, although there are many hotels around that seemed nice and which cost similarly (Quinta Rufino is NOT a cheap guest house!!) The staff is made up of young, hippie like guys who are nice to you but are oblivious to anything that's going around.
If you stay here willingly you should have your head examined. Expedia should drop this listing.
