Juan was a gracious host who provided lots of helpful recommendations and was easy to get in touch with. The apartment is well-located, clean, and comfortable. I'd especially recommend it as a home base for anyone who is visiting Buenos Aires on a short stay, as it's very close to plentiful shops, dining options, grocery stores, cafes, and the subway. So you don't have to worry about finding any of the practical things, and you can focus on enjoying the best of BA.
