This shared apartment almost feels like having your own place because it's massive. Santa Fe and Scalabrini Ortiz are chaotic avenues full of buses, but the inside of the apartment is silent. I love the 1930s building which gives a good sense of what Argentina was like when it was swimming in money.
In terms of location, you can't do much better since the Subte entrance is right by the door and a supermarket across the road. It's about a 10-15 minute walk to Palermo Soho, less than 5 to the botanical gardens and 5 to the Alto Palermo, for reference. There's plenty of affordable places to eat out as well.
Would highly recommend to anyone who is working/studying around Palermo or who plans to regularly use Line D of the Underground.
