We will arrive at Aeroparque on a Sunday at 9:30 and our next flight only departs at 14:30.
1) If it's a sunny Sunday, taxi to Parque Tres de Febrero (Rosedal, Planetarium, Japanese gardens...)
2) If it's raining, taxi to MALBA.
Those were my first 2 thoughts. Any other options?
We have been in BA before, but not Recoleta or Palermo.
