I stayed at Modern Apartments Buenos Aires (Oct 2024) in Puerto Madero and had a wonderful experience. I booked a one-bedroom, one-and-a-half-bath unit, and it was super cozy and beautifully decorated. The apartment was spotlessly clean, with housekeeping offered twice during my 5-day stay. The WiFi was fast, and the split ACs were fantastic—much appreciated given the hot weather. The only downside was some noise on rainy days, likely due to being on the 8th floor. Overall, it’s a great option for a comfortable stay in Puerto Madero. Would definitely recommend!
