Hotel foz do Iguacu sold to us as a 4 star and ended up being more 2 star. Dirty horrible place with the odd cockroach running about. This was last century although I see the reviews on TA are still rather mixed.....the person that gives it 5 stars and says "historic hotel in beautiful grounds" has definitely got it mixed up with somewhere else....or is really the manager.

I suspect with the increase in foreign tourism since those days they might just have improved it by half a star.
We still had a great time at the falls but we were ripped off by our local travel agent and told her so when we got back.
