Ricardo is an exceptional Airbnb host. The apartment was overly spacious for 2 of us. He also leaves you a small jar of dulce de leche from his hometown. The location is perfectly centered in the heart of the city with multiple means of transportation to the other neighborhoods of the city (La Boca, San Telmo, Recoleta, Retira, Palermo). I highly recommend the Buenos Aires Tourism bus.
Also, the night shift concierge, Angel, is a great person. Please take a few minutes of your day to speak with him. Also, be sure to take a photo with him at the end of your trip! Take one on his phone, too.
