I spent a few months in this apartment and loved it.
The location is perfect – you're right in the middle of everything, with amazing parks and great restaurants all within a 10-minute walk. The apartment is very modern and has everything you may need, including a comfortable place to work with great 300Mbps internet, two ACs, plus coffee and washing machines. There's also a small gym, sauna, and swimming pool on the rooftop. Agus is one of the best hosts I've ever met; incredibly responsive and super friendly. One small thing I should mention is that there's construction going on at the end of the block, but they only work for a few hours a day during some weekdays, and you can't hear them with windows closed. Overall, I'd definitely recommend it to anyone visiting Buenos Aires.
