Vivi's apartment is a great place to stay - the bedroom was large and clean and the bathroom is also very clean. The kitchenette has two hot plates, a microwave, toaster oven, and blender (perfect for making licuados!), and there are lots of panaderías, grocery shops, and a fabrica de pastas and a carniceria within two blocks. Vivi is very kind and friendly - my first day, she and Elfa (another visitor) oriented me to the neighborhood and showed me where the mercados, lavanderia, etc. were.

If you're interested in learning tango, I recommend her classes, as they're small and the people are friendly. For the Spanish-impaired, Vivi will explain things in English as well as in Spanish.

Regarding the street noise, the colectivos are loud during the day but at night I didn't notice them at all and had no problems sleeping.
