I ended up in la Barraca after another hostel gave my reserved room away cause I booked over the phone, so I was quite distressed and desperate. Ciara was very helpful and showed the rooms available. Price/quality is super! The house itself is so nice and clean, it gives you a very homey feeling.
It is about 15min walk from the center of town, so take that into account, so you won't complain later on, cause this shouldn't be a downside, in Bariloche it isn't such a bad thing to be away from the whole touristy scene.
I went back there after I went for a trek, cause I liked it so much!
