Amazing location in safe Puerto Madero area, close to restaurant, coffees, a large supermarket, San Telmo, La Boca, everywhere you need to go to if you are visiting Buenos Aires.
The apartment is better in real life than pictures, bedding was great and the AC worked very well during summer months.
The building has a 24hrs concierge and two large swimming pools that are well kept and quiet, and there is lot of parking space in the area.
For sure I wouldn't stay anywhere else when I visit Buenos Aires.
