Much recommended! I didn't met Danilo in person, but he always answered my messages very quickly and we arranged all the details easily.
His parents received me (most friendly people), showed everything, gave directions for supermarket, drugstore, etc.
The apartment is exactly what the pictures show. Very clean, the windows provide plenty of natural light, enough space for three, fast internet, very well located (stayed in others neighborhoods in past Buenos Aires trips. I can say Recoleta is the best!).
The experience in one word? Perfect.
