The place was exceptional. A small cozy studio, very well located, has a nice balcony, very well decorated. Good quality furniture, comfortable bed, hot shower, etc. Everything perfect. The location is also great, close to the subway. The Santa Fe Avenue is a bit busy and ugly, but is still worth it. I'd highly recommend staying there.
When we got there, Marcelo was waiting for us and showed the apartment, gave a few tips, etc. They even left us some fruits, water and cereal bars. Very nice reception! :)
