Joaquín is a great host and the place is superb. The pictures are very accurate and you are literally in the middle of Palermo, close to malls, pubs, restaurants. The location has 24x7 security and they are very attentive when you arrive/leave the building.
We made a few requests to Joaquin and he always took care of them.
Definitely a place we would like to come back when in Buenos Aires.
