Maria's appartement in Buenos Aires was beautiful on the inside, near a nice variety of ideal restaurants (right around the corner), and was a good stay-in apartment for work.
Hint: There are some incredible restaurants (one across the street from the park) that have been there for many decades and have very authentic, family-owned Argentinian food. They do accept credit cards. There is also a market down the street that will accept a card and has basic amenities, snacks, packaged foods. There are also many meat stores south of the apartment (go during the day time only) that will sell fresh meat to you.
To note: I wouldn't recommend this apartment for a first-timer's visit to Buenos Aires. We were warned several times that the neighborhood is unsafe, especially for someone who doesn't appear to be from Argentina. Deliveries were not available for us in the evening due to safety concerns.
