This absolutely beautiful cultural center, in what used to be the Central Post Office, is as beautiful on the inside as it is on the outside. And, as usual, it's even better cause it's free.
There are many art exhibits that change throughout the year, so there's almost always something new to see. The building itself is gorgeous, even if there wasn't any art installations it would be a worthwhile experience to drop by and check it out. The exhibits themselves are great too, and it can be a bit hard to navigate the six floors but just ask any attendants! The information desk at the ground floor does a great job to help visitors get their free tickets (you have to reserve them online beforehand, though) for the many musical performances the center offers.
The many performances are absolutely amazing, I recommend signing up and going to as many as you can even if you're not familiar with the artist or the musical style, cause they're always fantastic. If you're not that interested in music, it's a great chance to enjoy the atmosphere and the architecture of the many rooms. The sala sinfónica in particular is gorgeous.
I reiterate, it's free. I'm beyond amazed at this wonderful achievement, of making these cultural centers / museums free of charge, making the very clear statement that art and culture is for everyone. There are also classes that you can take there, dancing and exercise and who knows what else, all available to the public (though you probably have to sign up beforehand, so check their website).
Like any museum it's closed on Mondays, unless it's a holiday, in which case it's closed on that following Tuesday. If you're in Buenos Aires, either visiting or living here, drop by. This place is gorgeous.
At least just come and use the restrooms, I promise you'll stick around.
