We liked the appartment where we stayed for 18 days. It was not big, but cosy, with a sunny balcony and small kitchenette. The district was safe, in the walking distance from bus and subway stations. Emiliano speaks very good English. He and his mother were both hospitable and ready to help. They provided us with the map and public transport travelcard.
There are different foodstores and a pharmacy nearby. We recommend this place for a shorter holiday or visit to BA.
