Everything worked pretty great, altough it was a bit confusing, since the apartments are almost the same size but the prices changed a little (so, I actually didn't know very well for which one I had pay because the photos are all together in the website) and I only wanted the back ones because they are more silent.
The area is pretty good, near to Plaza Serrano and Alto Palermo.
The apartment is really good, confortable, clean and very very new! Claudia is a great person, she took care of everything. She was there when I arrived and she helped with everything I needed.
It was a great oportunity to stay in this apartment! Thank you Claudia!
