We had a really bad experience!
The price was very Low and the location ideal, BUT...
The room was in bad condition with filthy bathroom, dirty bed sheets and overall badly maintained. Apart from this there were bugs All over the bed sheets and floor.
But that was not the worst part.
We booked through hotels.com, which means the price was arranged before we went. However the owner (maybe) Tried to trick us into paying too much. The price was 21 dollars, but he tried to charge us 1.600 argentine pesos (with todays rate it should be 1.250) after arguing with him for some time, we agreed to pay 1.350.
We gave him 1.500, but as he didn’t have change, we agreed that he would give us the rest the next day.
After one day, we decided to stay one more night, since it was cheap and with a good location and we had had a long day and the falls. We agreed to pay the same price. The next day when we had to pay, he remembered nothing about our agreement, nothing about the money he owed us and would not listen. He started to get aggressive. But luckily, someone who new him (not employed) came and helped. We ended up paying the right amount, but he was VERY reluctant.
