I enjoyed the Apart Hotel Via 51 in the offbeat track and a few blocks away from the Teatro Argentino for opera. The hotel is reasonable. Rooms are clean and small but a nice place to stay for 2-3 nights. I am not sure of the size of all rooms. The staff at the front desk is very nice and security is provided as in most places. It is a few blocks walk from governor's mansion. opera and cathedral but walking is good.
