The apartment is in a fantastic location for any Tango dancer. I specifically picked the location because it was 2 blocks from Club Villa Malcom, 2 blocks from La Viruta, and a few more from Salon Canning... I walked to and from all these locations late at night and had no trouble.
It is 10-15 minutes from some amazing restaurants in the Palermo SOHO area (Burger Joint has amazing burgers, and Don Julio is pricey but worth it).
It's a bit of a walk to the Subways, but you can always take the bus a block away to get to the Subway Station if you don't want to walk.
The apartment is simple, clean and perfectly fine for my week long stay in BA. Water pressure is good, AC works great, it has a nice view, and because you're so high up, you don't have to worry about bugs (even if you leave the window open).
My only suggestions are to have slippers as the floor is slippery when wet or when you wear socks. To remember to close the inner elevator door every single time (if you're not used to such things), and to figure out the laundry situation early if you don't speak Spanish.
I would definitely stay here again if I go back to BA.
