I had a great stay at Luciano's apartment. It is quiet and light and very close to several Subte lines. A short walk takes you to Recoleta cemetery and the Subte lines take you anywhere you'd probably want to go. I didn't need to have any dealings with Luciano or Ricardo while I was there but they were able to give me a late checkout, which I very much appreciated. It was the ideal base from which to explore BsAs.
