Rocio & Nicolas´s place is just great. The apartment is perfectly located, close to a Subway station (Subte), and with an amazing view. Communication with Rocio was fast and getting there was very easy. Everything was as advertised. Around the corner you have serveral good options for a quality and budget-friendly meal. I'd recommend La Dorita, a parrilla (bbq) with a good menu and several options.
If you want to stay close to everything, but at the same time get a feel for a real barrio, it´s an excellent choice. Just, one other thing, I worried a little bit about the noise, since the building is on a very busy avenue. Don´t worry, there is hardly any noise. I´m a light sleeper, and I slept like a log every night.
