The apartment is as shown in the pictures. It is clean and well lit. It sits on Avenida del Libertador and offers glimpses of Uruguay across the river. I liked being on the Ave (as opposed to a side street) with the city views. (And the Ave quiets down at night.)
The neighborhood is quieter than, say, Palermo, which is more to my preference. I found everything I need in with a few blocks of the apartment - groceries, patisseries, laundry, coffee shops, pharmacies, nice restaurants, and casual eats. There was no need to travel very far if I wasn't up it. In short, it was a great base from which to explore.
The doorman is extremely friendly, but doesn't speak English - so practice a few phrases to key get the keys!
