Amazing huge place. The apartment has a central area that opens to the sky. We enjoyed wonderful mornings in the common area drinking the excellent Argentine coffee in the morning sun. There was a tremendous amount of space as well as rooms to stay. The area would be great for a large group. We had 3 couples with room for easily 2 more. Lucy and Manuel were absolutely delightful. If you were inclined to cook the kitchen was nice and they had a separate grill for cooking meat etc. You will need to polish up on your Spanish for meaningful conversation with them.
The air condition in two rooms was marginal but with the multiple choices we just pick a different room and had no problem.
The neighborhood was good but NOT the best place to roam late at night. Otherwise we felt perfectly safe. Likely that statement would apply to all of BA. I recommend the place without reservation. We plan to return next year!
