We really liked it.
The apartment was perfect for a hiking vacation. Clean, warm at night, practical kitchen, and a nice steaming hot blasting shower after a day of hiking. Even better, located right over the top of a outfitters store (Patagonia Hikes) for hiking clothes or equipment. The location is easy walking distance to some of the best places to eat in El Chaltén and shopping to. The best thing about this apartment is that the local manager of the apartment and the persons that work in the store are very helpful for information about places to go, the best hikes once done with the obvious Fitz Roy Laguna de los Tres, and other local information needs.
And the wireless work very well.
I would not hesitate to return to this apartment.
