We had a fantastic stay in this apartment and would highly recommend as a home base in Buenos Aires.
Location is great - walking distance to parks and all of Palermo which is full of great restaurants and nightlife. Easy access to most major sites in BA on foot, taxi or subway.
Incredibly responsive and proactive hosts.
Apt is exactly as it looks with great views of the city. Very safe. Pool is nice, Gym is nice. AC works great.
Only negative
The 2nd bedroom with twin beds doesn't have a wall but more of curtain as it overlooks the common area downstairs. It works ok but if you really want privacy for each bedroom this wouldn't work. We had our kids with us so ok.
Would definitely rent this again and highly recommend.
