I've stayed at Juan's apartment for five weeks. it's a lived in apartment in a lived in 24 story high rise in the business district of BA. It has grit and noise of s metropolitan city. It's close to many interesting sites, theaters, museums all within a walking distance. There's a hostel two minutes away ( on Av De Maya) where you can take Spanish lessons or even see if you can join some of the hostel's activities. I saw a soccer game and did a city bike tour and attended daily Spanish lessons with them.This is a busy, active side of town if you want an unfiltered cultural experience...look no further.
