How to spend 2 days in Buenos Aires

Thirst of all I would like to recommend to visit the central street of the city named July 9 avenue. This is the biggest street in the world. Also you can find many sightseeings here. There are Teatro Colon, Congreso de la Nation, Botanical Garden, El Ateneo Grand Splendid and Obelisco. There are many beautiful authentic buildings. Approximately it takes 2 days to observe all the places. #buenosaires #historical #historicallandmarks #familytrip 📍Address: El Ateneo Grand Splendid: Av. Sta. Fe 1860, C1123 Cdad. Autónoma de Buenos Aires 💰Average Price per Person: not so expensive, because most of sightseeings are free
