The first time I stayed in this hotel was in 2008, when I spent 4 nights in Buenos Aires, and it was a very good experience. Last year, going to Brazil, I had to spend 1 night in Buenos Aires before heading to my final destination, so I decided to stay there again, and also booked another night on the way back, to rest and have a shower between the flights from Brazil to Australia. Unfortunately, it was a bit of disappointment this time. The location is good - it's in the city centre, close to everything - but it seems the hotel has not been refurbished or taken good care for a while. Apart from the lobby, all the rest is old and looks kind of abandoned. The room we stayed the first night was creepy, as are the corridors and the lift. Breakfast used to be better, but you still get good food.
When we returned for the second stay, we were upgraded to a better room on what they call "Club Las Naciones" - and this one was very nice: bigger, clean, comfortable, with a very nice and clean bathroom...it was a shame we could stay for just a few hours before heading to the airport.
The staff was helpful and friendly as always.
We still would recommend this hotel because of its location and price.
