Felicitas and her husband were wonderful hosts. We were greeted by her husband upon arrival, and he gave us a great overview of Buenos Aires, complete with a map of the city and a metro card--and a little present we enjoyed, too: a bottle of Malbec. We did not meet Felicitas, but she was available to answer all of our questions (like how to get to the San Telmo market, or where to buy a bus ticket to Mar Del Plata) via WhatsApp. She was always very friendly and helpful. The apartment was just as pictured, quaint and clean (close the windows at night to avoid bug bites). It was located close to buses and trains, and a very short bus or taxi ride to main attractions. There is also a nice bakery downstairs, and a supermarket around the corner. We frequented both. On our last day, our taxi did not come, so Felicitas's husband drove us to the bus station at 6am, and helped us find our gate to wait for the bus to Mar del Plata. He was very sweet. Great hosts! I highly recommend this place to anyone who is looking to stay in Buenos Aires.
