The check-in was very quick because Federico was waiting for us in the apartment. No problem with check-out as well. The apartment is near the railway, which was an advantage for us as it was easy to get to the center of BA and go out to Tigre, Olivos (and super cheap). The noise from the railway maybe bothering for someone, but for us it was not a big problem.
The bed and the sofa were comfortable for sleeping.
No washing machine, which turned out to be a common thing in BA)) But there are many lavaderias nearby.
An air condition in every room was a good thing!
Barrio Chino is within 10-15 minutes from the place. Coto supermarket is within 8 minutes walk.
Federico is very friendly and always stayed in touch.
