We did not meet Gabi during our stay. Her parents let us in and showed us around. We were presented with several forms to sign regarding use of the apartment and inventory lists. That felt a little weird otherwise the apartment was comfortable and has a great balcony with nice views. We enjoyed breakfast most days there. There are many cafes and restaurants in the area. We liked Guaresnei at Carranza & Nicaragua for coffee and croissants. Da cordons, just steps from the apartment is great for dinner. We celebrated Christmas Eve there. The subway is about ten minutes away. We used it many times to go to city center. For us a highlight of a week in BA was the ferry to Colonia, Uruguay. It is a cute town that retains its colonial appearance. The ATMs there eject $100 dollar bills, useful if you are low on cash and want to take advantage of the "blue" rate. It was 12.6 pesos to the dollar in late December 2014. The official rate was just 8.4. In Colonia the merchants are happy to accept $ or AR pesos for payment. No need to exchange for Ur pesos.
