Thanks to saint and other who took time to answer my question (both on and off the board) re apartments. We are going in October and will give it a try. I was in BA in April, but had to cut my trip short so my stay was only three days. We expect to be there at least ten days this time and will truly explore.

One further question. I will break off for a couple of days to take my daughter to Asuncion, Paraguay where she will spend a month with family friends. Is there any advantage/disadvantage in buying the tickets EZE-ASU in advance (e. g. through Aerolineas Argentinas) versus waiting and buying them in BA? We will be getting one r/t for me and a one-way for her as she will depart to the US from ASU.

Again, thanks in advance. Will post on apartment experience after return.
