We spent three nights at the Sheraton in Iguazu last month and I was not impresssed. The first night we were upgraded to a suite as a platinum upgrade and the last two nights were in a forest view room that was not spacious, not as clean as it should be and had black mold in the bathroom. The night manager told me we would be compensated with 8000 SPG points, (which I am still waiting for) and was a very pleasant person, but giving someone a room in that condition (especially a platinum member) is quite inexcusable. The location was excellent for entry to the Argentinian side of the falls and that was probably the only redeeming factor for the hotel. The hotel is quite dated and really needs some sprucing up. The food was okay, nothing great. The pool area is acceptable, but again nothing fantastic. Considering what a prime location they have, they should really invest a few dollars and bring the hotel up to par. The hotel in the park on the Brazilian side (not an SPG hotel) is much nicer and I would stay there if I ever go back.
