Great central location. Puerto Madero is perfectly safe, even into the early hours the morning, albeit a bit sterile.
The flat itself is bigger than it appeared (at least me) in the photographs. It's quite quiet and the balcony over the promenade is very relaxing place to spend your time.
The building also has a gym. There are no laundry facilities though and you'll have to use the laundromat down the road.
Cafes and convenience stores are right outside.
There is no concierge at the desk which is good for privacy but you need the key to exit the building and you can't buzz someone up.
I was stuck in the building with Uber outside and the key in the flat as instructed but there is no internal buzzer for the concierge. I had to bang on the window to alert a passer by so he could buzz the concierge, who argued for minutes before letting me out.
