If you like to be outside, this place is hard to beat in BA. Amazing terrace. Seba and Dino live just downstairs, so communication and check in/check out was very easy. Núñez is on the quiet side, but there are some really nice restaurants around there, including La Madonnina just across the apartment, which has amazing pastas. The place is close to the highway and libertador, making it very easy and fairly cheap to uber around.
There’s a laundry machine in the apartment and you can sundry your clothes in the terrace. Very convenient. Amenities (such as Internet and a/c worked well). Mattress was firm.
