Alto Palermo isn't dog-friendly for me, so i haven't been inside, but the security guards said they'd let in small dogs (Argentines love tiny <20# dogs) or service animals...but mine is almost 100 pounds, so he gets looked at a lot!
the theater looks nice and the inside seemed immaculate, and there is a chain Megatlon gym inside that looks massive!
lots of beggars in that area, and the occasional bum sleeping on the ground, but overall trash on the ground was minimal.
and echoing what
@Vince said, i feel a noticeable difference in Palermo SoHo/Hollywood with locals looking at me and treating me differently. living in Villa Crespo for a couple weeks, no one seems to notice me until i talk with my accent. people often approach me and try to speak really quickly, and then they realize i'm an Expat with bad Spanish. i got asked if i was Brazilian a few days ago, which has never happened in my life. but SoHo just seems like there are a bunch of people talking English to other tourists, there are 'fancy' clubs and restaurants with high prices, and you aren't going to fit-in. 2 nights ago in SoHo there were bouncers/security guards at the entrances of the resto-bars, i think because it was a holiday, but they weren't letting some people in, and it just wasn't my type of scene. that being said, it's not bad if you do! if you like
Scottsdale AZ's scene of nightclubs and being seen, status symbol, $40 USD cover charge to wait in line, and $15 USD beers, you'll like SoHo. if you want to be treated more like a local, Villa Crespo has been easy to just live a normal life!
i'll report back on Monserrat in 2 weeks, but so far the walk on Av. Corrientes by the Obelisk was crazy at night, like downtown Mexico City or Times Square in NYC! the Monserrat area has a lot more piss smell on the sidewalks, lots more trash than Crespo or Palermo, and i walked by some obviously-drugged-up nasty-looking folks on some streets like
Talcahuano that made me decide i'd never live or invest around there. i haven't seen stuff like that in my 2 weeks so far.
