We stayed at Fernando's place for nine days. The neighborhood is absolutely fantastic if you like exploring cobblestone streets, with the Plaza de Mayo, Puerto Madero, Ecological Reserve, Mercado de San Telmo, Modern Art Museum, and tons of cool cafes and plazas within walking distance. The subway and our Spanish School were an easy 10 minute walk away, and the Feria de San Telmo (Sunday open-air market) is just out the door. The apartment was perfect for our needs - quiet and clean with a fast internet connection. We never met Fernando in person, but he was very responsive by email and we had several friendly interactions with Mrs. Aida, who also answered several logistical questions. A great value. We hope to stay here again on our next trip to Buenos Aires!
