This was the perfect location for our stay in BA. The mall and Recoleta cemetery are about a 15 minute walk. Port Madero is maybe 30 minutes. The apartment is exactly as described by others and very comfortable.
If you leave the building and turn right, there is a small grocery store about 50 paces away where you can buy most things including beer and wine. If you continue on to the end of the block, there are two fresh fruit and vegetable stores. Turn right, and a short way down the street is a bakery with all sorts of delicious goodies. Tip: You need a key to both enter and leave the building so it is very important to always have the keys with you. Another Tip: The stairwell lights are on a timer, to activate them, push the small orange button on the wall.

Overall it was a great experience. Thanks Ana!
