Carlos greeted my family the moment we arrived to let us in and give us our keys. What's important to note is he let us check in a few hours early and the day we left let us check out more than a few hours late. We would have been stuck rolling all our stuff through BA if it wasn't for his flexibility. I know it always possible, but if it is, he will accommodate you.
The place was exactly as described, clean and simple. The terrace is amazing and I recommend having dinner or at least drinks out there one night.
We didn't explore the neighborhood too much as I had my own agenda closer into the main tourist part of town. If you want to taxi or uber to Recoleta, the other end of Palermo, Puerto Madero, etc, its a 15-20 min drive. Nothing too bad at all, but it did add up after 5 days, so also consider public transport.
Thank you for your hospitality Carlos and for checking on us and answering all my questions within minutes. Until next time!
