My fiancé and I stayed for 3 days and we absolutely enjoyed our stay in Buenos Aires! We've stayed in airbnbs all over the world, and this by far, is our favorite! Very spacious with a well equipped American kitchen, good sized bathroom, washer, and heat. The king sized bed was very comfortable. Check-in was very easy and flexible. We met with Gaston at the apartment who gave us a tour of the apartment and reviewed over recommended places to eat and visit during our stay. They also included maps and had a sube (subway) card available for us to use so that we didn't have to pay to purchase the card. They also have wine and some other things you can purchase at retail prices, that are readily available at the apartment. There is also a nice sized grocery store near the apartment. Gaston was very communicative and responsive. I highly recommend staying at Gaston and Barbara's apartment!
