No hotel could be better located: 2 blocks away from Calle Florida, 3 from Av. Nueve de Julio. Large room with above-average beds and a wall-to-wall window with a spectacular view of the Obelisk. Large TV, countless cable channels. All staff members spoke good Portuguese (the hotel is overwhelmingly popular among Brazilians). Nice breakfast with good coffee and delicious facturas. Got a bill for a can of juice (from the minibar) we did not consume; reported the error to the front desk and the bill was immediately cancelled, no questions asked. Found a cockroach in the bathroom. Water temperature was a bit hard to control. The "business center" is just one (large, comfortable) room with one internet-enabled computer.
