Stayed there 4 nights in January. The hostel is very basic, basically you get what you pay for (although there are better value hostels in Chaltén, but all of them where fully booked when I went. The kitchen is ok, but the main lack of the hostel is a common area where to hang out and meet people (there is one but quite remote and super small). Lautaro, the guy running it, is very nice. All in all I'd just try to find somewhere else but if you don't staying here is not that bad.
Great stay. Would definitely go again. Ahmet is the best!
Bathrooms could be better ,but great choice otherwise all in all. Awesome location near plenty of bars and fun area. Staff is helpful and friendly. Thumbs up if you want to escape the budget getto of Montmartre.
