Thanks for the info. It's at the intersection of Virrey del Pino and Av. Luis Maria Campos.
And yes, bars and young folks are some of my primary concerns, haha. I wanted to get a place in Palermo, but my Argentine friends live in this area of Belgrano and they helped set this up. I figured I would give it a shot, meanwhile looking for something closer to downtown as a back up.
Also, do available apartments and rooms for rent become drastically more sparse as September and October roll around? I've heard this is the height of the tourist season.
