The hotel is good for the budget traveller going to the Iguacu Falls. The whole area near the hotel seems to be a bit older - not run down exactly but just older in general, so the decor and the buildings reflect that.
The greatest part about the hotel is the Wifi, followed by the free breakfast. The location is also a plus since it's very close (5 mins walk) to the bus terminal (TTU). This is great for accessing either the Brazil side of the falls (take the 120 bus), the Foz do Iguacu Airport (also the 120) or the Argentinian side of the falls (via the international bus that stops outside the TTU). There are many bars and small restaurants on the street so you can go eat, but aside from that, there's really not much to do.
Big down side of the hotel was that my electric adapter was too big to fit into the socket. I found this applied most places but at the hotel in Rio or Sao Paulo, there was at least one plug that I could use. I ended up having to go down to the lobby to charge my devices.
The other big down side was the smell. When I first entered the room, there was a distinct odor in the room, which I had found out was sewage, coming from the shower drain. I closed the bathroom door and left the ventilator on to get rid of the smell. It was okay after that, but I guess that's rural Brazil for you...
All in all, a generally okay stay. Super good value for the money though.
