Wifi was bad - whatsapp text msges (no photos!) was the maximum available. It's not a problem of the hostal tho, the whole town is struggling with connectivity due to its remoteness and weather. One afternoon, even electricity was out in the whole town. That's deep Patagonia! Didn't mind disconnecting actually.
Pretty place, big room (stayed in the double), good breakfast and great location opposite the huge granite wall across the river. Especially the (half-sized, but still....) bathtub was an amazing luxury to have after a long hike.
It's not the cheapest place in Chaltén but I didn't mind paying a little more for being very comfy in this beautiful town.
