Me and my friend stayed here for two nights two weeks ago during a visit to see Iguazu falls, and it was great for a hostel. We booked a double room with a private bathroom, it was basic, as we were expecting, enough space, comfy bed, plenty of hot water, breakfast, lockers, everything you need really.
It was 5 minute walk to the central bus station where you get the night buses from Buenos Aires or Brazil etc., which is next to all the streets with shops and restaurants, but far enough away to be quiet which I liked, and felt very safe. We originally walked into the Bambu hostel which you come across first, (its sister hostel) and they have a pool and have bbq's in evening where you can go and eat. We did this on the second night and had the biggest steak I have ever seen in my life, it was the beast food we'd eaten during our travels and good price. But best of all the guy that runs it helped us with our bags to our hostel, which was great as we are those stupid travelers that take suitcases and far to many shoes (and about 5 bottles of booze - but we didn't tell him that when he asked us what we had in our bags!!) The reason for this is we were away on business tagging on some whilst in that part of the world, and not backpackers. Bambu mini has a bar and garden courtyard area.
When we arrived the lady on the front desk was fantastic, she gave us so much information, we didn't have to ask anyone else anything. She gave us a route to take round the Argentinian side of the falls, and how to get their etc. We had already booked to go with a tour company to see both sides of the falls, as we weren't sure how accessible it was before we got there. But you could just go by yourself without a guide easily, although there is a lot to do in a day an its a huge place and there isn't one part thats not worth seeing, you must do it all, so it helped us having someone else leading the way and making sure we saw everything.
If you go to the falls, allow one full day to do Argentinian side and half day to do the Brazilian side, both sides must be done. Also if you're brave do the speed boat trip, but take a towel and a change of clothes or swimwear or something, you get completely soaked and don't have enough sun or time to dry off before coming home and sitting on a bus soaked through. I have never got so wet in my whole life, not even in the shower!!! Its quite mad as you don't actually get to see the falls from that close because you can't even open your eyes. But if you have young kids I would not recommend it. A family were on our boat with a toddler, she was terrified. In fact we got soaked both sides of the falls on pretty much every part we went to!
