I had a great time in Santiago's apartment in Recoleta. He, along with his wife Lidia, were very friendly. They explained everything about the apartment and what to do & see in the area. They provided a map, a subte (subway) card and suggestions for food. They could not of been nicer.
The apartment itself was perfect for my needs. It was in a great location, close to Recoleta, the bus/train station and subte lines.
I would definitely recommend staying in this apartment.
