Perfect! Alejandro's place is just as listed, in photos and in description. The apartment and building are a true "porteño" experience, with friendly doorman, good kitchen for cooking, great AC and wifi, and super tele for a World Cup match! Alejandro communicated great from the very first, fast and professional and friendly, and was flexible with check-in/out.
The neighborhood is not a tourist destination in itself, but it's kind of perfectly in the center of the city, easy to get to all the good spots.
The small park on the corner is really special and unique in Buenos Aires, unless you are right on one of the bigger parks. Great for running around the outside, or working out or drinking "maté" in the middle.
I would definitely stay again!
