We arrived at the bus terminal in the dark, after a busy day, with no idea where to stay. Heading down the hill towards town for 2 or 3 minute we spied this place. Too tired to negotiate we payed 300 peso per night for the room which was clean and as described in other reviews.
Our room was behind reception so could be a bit noisy from road but was close enough to get weak & patchy wifi signal in room. Stayed 3 nights, room not cleaned in that time. Owners have no English but friendly enough. Breakfast meagre.
Best thing is to visit falls just walk to bus terminal, pay 70peso per person for return ticket to falls and bus takes you to park entrance. Entrance costs 170peso per person and they don't take credit cards?! So have the cash. If you get the card validated it can be used the following day for half price.
