Baires Apartments (a temporary rental and real state) offers phone rentals and, as you mention, they send it and pick it up for free (to/from the hotel, or to/from the airport).
The Cell phones are free of charge. You just pay the calls.
The rates are of course more expensive than a normal cellphone you can buy and top-up, but still not terrible:
Locals: AR$ 1,50 | National: AR$ 1,99 | Argentina - Mercosur AR$ 3,19 | Argentina - U.S. AR$ 3,49 | Argentina - Europe: AR$ 4,59 | Argentina - MΓ©xico-Venezuela-Israel AR$ 3.79 | Incoming Calls AR$ 1.00
Cellular rental: AR$ No Charge | Insurance: AR$ 19.00*
So local calls would be $1,50 pesos or, at today's change rate, 0.19 US Dollars.
Another company is For Rent Argentina, phones are also free but the price per minute doubles.
