On Sundays this is the best plan without a doubt. In the neighborhood of San Telmo you have a great street market with antiquities, music, tango dancers and a great atmosphere.
The first thing I did in Buenos Aires was falling in love with this city. If I should describe it in 1 word I'd have 2 say "Beautiful", but it's not only beauty what u gonna find there. First of all I saw the buildings, all of them are so pretty, that maked me wanna life there. Then I went shopping, in every single store I wanted 2 buy at least 1 thing. After that I went 2 eat something: Delicious! And when I get 2 the hotel I sleep as well as I had ever done.
So my tip is: GO TO BUENOS AIRES!
I just wrote about Buenos Aires, but I forgot to tell you about some places u can't miss.
First of all go to do some shopping in av. santa fe. Then make a short visit to the Ateneo library to buy a book or just see the place, couse it's amazing.
I also recommend to go to Abasto, it's really nice!
And remember when u are there to see every building, couse every one of them is beautiful & also gotta watch the ground, couse u may find some lovely things in it, there's always gonna be a surprise!
