Puerto Madero is NOT worth it
Few infraestructura, cheap concrete-Durlock-towers with "smartmarble" apearance and FAR AWAY from real value and willing chicas.
Montserrat is THE FUTURE development as it had always higher values than "trendy" San Thelmo in the Argentinean market.
Plaza San Martin still with some (not many) offers below usd 1.500/ sqm.
Puerto Madero is a unworthy real-estate bubble.
Puerto Madero= the Las Vegas of Argentina
You humiliate the porteņo culture by hiding in a such artificial barrio. Open up and get to know the poeple and the city, even if it involves some risks, is has so much else to offer. Oh, I forgot, you are americans.
