It was the best option to stay one week in Buenos Aires and I highly recommend this place. Everything was perfect: attention, communication, apartment itself. Andrea, Catalina's mother, helped us a lot with check-in and check-out, with advises about city (there is hand-made tour guide!!) and places to go, and everything was right in time and with open soul. It was a pleasure!
Also there is great pool on roof, so in summer is the best option!
Hard to say more better words, just need to try it and feel yourself like a local. Went to lezama park, walk to Puerto madero, or go to la boca - everything is nearby.
