I stayed at the Argentino Hotel in Piriapolis in February, 2006. Fortunately, we only stayed for 3 days. It was awful! Even when we rented one of the "recently renewed rooms" and one of the most expensive room in the hotel.
The building resembled a public house or a hospital: very tall ceilings; huge corridors, with no furniture; floors were old and damaged, elevators were old and did not work properly.
Rooms were not well appointed. In those rooms that were "renewed", small TVs were placed on some iron-made tables which, certainly, had nothing to do with the old fashioned style of the hotel. This was just one more detail that showed the poor quality of the hotel. There were no blankets available: just some small ones, similar to airplanes blankets.
Bathrooms´ windows faced the corridors, so you could hear noises from the bathrooms when you were walking the 150 m corridor that stood between your room and the elevators. Regarding "renewed" bathrooms, pls expect some renewal from the 70´s, nothing after that. Hot water was missing sometimes. The quality of towels and soaps was really poor! Not even in some cheap budget hotels I had found stuff like this.
Pools were ok, even when they needed extra maintenance ( painting and some other details were missing).
Breakfast was ok, nothing great but not bad.
By night, there was a live music show that gave some fresh air to the overall depressive hotel.
The exterior of the hotel is impressive: it looks really nice. Unfortunately, the interior is not quite the same.
I found no better hotel at Piriapolis: the whole city lacks a good tourist infrastructure. Just budget hotels. Caffes and restaurants were also modest and did not seem very clean.
Beaches were good.
