We stayed here for a short trip to Buenos Aires. Our flight arrived early in the morning and the front desk agent was extremely wonderful and allowed us into our room early so we could rest/shower after 24+ hours of travelling. The staff in the lobby bar was also very wonderful and kind to us.
It is a beautiful property, from the lobby, to the bar, to the restaurant, to the stairs, to the rooms. We found the location to be great, along a major avenue, close to National Congress, and walkable to many other areas of the city.
They were also able to arrange an very reasonable rate for a Tango show and dinner, with transportation included.
