Cris is the best host I have yet to encounter on Airbnb. She was kind, helpful, and even showed us around the neighborhood. The apartment is much bigger than I expected and was very clean. The neighbourhood itself is very quiet and a great escape from the craziness of the centre. It's a bit of a trudge to get to the centre on the train (fortunately the train station is two blocks from the flat), but well worth the adventure to see a larger part of the city --the true Buenos Aires-- that travels rarely see.
Also, her English is impeccable!
