It's the second time I've stayed at this place. The location is perfect and the apartment is great and quiet. I was working for a few weeks during my stay and it's very comfortable to do that as well.
It's very close to everything, you can walk to whatever you need and you have all types of public transport nearby. The area is also safe at night.
Federico is always responsive and replies fast. I'm planning to stay here next time I come back to Buenos Aires.
