There's no doubt in my mind that the best thing about Buenos Aires is Cynthia and Jorge. Before our arrival they guessed our interests from the emails I sent them and prepared an itinerary for us that allowed us to see everything we were interested in in the city without killing ourselves, and they added things only a local would have thought of. Their generosity with their time was both astounding and touching, and I hope to one day be able to return them the kindness when they visit the US. Within a day we were describing them not as our hosts, but as our friends. The apartment is marvelous and the location is terrific, an easy walk to the Subte and with restaurant and stores everywhere. BA is a noisy city, and at the moment i write (May 2014) there is construction going on down the block from the flat, but once that's done this is as peaceful a spot as you'll find. I can't imagine why anyone would want to stay anywhere else in Buenos Aires.
