Puerto Madero has little appeal if you ask me, especially if you want green space. If the company's paying I'd look in Barrio Parque or whatever the area is where all the embassies are, or Botanico but closer to Libertador. Close to parks, lots more life and neighbourhood feel. Or get a house in Belgrano / Nunez. If their paying, you could get a house with it's own green space --w hy would you go for Puerto Madero, which is inconvenient to almost everything else in the city? PM maybe for offices, but living, forget it.
