Ana Inés was the perfect host. I stayed at her place for 7 nights. At the first evening she showed me around. Her place is very close to the subte (subway) and plaza italia, where many buses go by.
When ever i needed help finding a place or had trouble Antia helped me out.
The flat is very nice, the room quiet and the neighborhood is very safe.
If I'm going back to Buenos Aires, i will stay here again :)
