You'd love to stay in this apartment, especially if you're a tango dancer! 10 minutes walking to La Viruta and 15 minutes walking to Salón Canning. Also there're lots of cafes and restaurants on Armenia street.
The neighborhood is safe, the SUBE (metro) is close. The apartment is clean, beds are soft. It is good equipped for a long stay, has a washing machine, iron, air conditioning, hair dryer, etc.
I highly recommend you to stay here!
