This is a very cool and interesting place to stay. If you like Tango or want to learn it, it's the perfect fit! They have a studio with tango lessons and parties. But even if you're not into it (like me) you meet a lot of interesting people from all over at La Maleva.
The area is more quiet, although there are a few places for going out at night. But the Metro station is very close and buses bring you to Palermo if you want to go to bars/clubs.
