Martin was an exceptional host - extremely responsive, and went above and beyond to make sure that our stay in Buenos Aires was comfortable and cultural! His place is ideally located in the beautiful Palermo district close to the park, the Palermo Viejo markets and sidewalk cafes, and the Subte metro system. And his recommendations for dinner at the Parrilla and the tango place (Complejo Tango) were perfect. All in all a fantastic trip to BA, can't wait to go back again!
