The flat is in a great location, walkable distance from many restaurants, bars, ice cream shops, supermarkets, etc. in the Palermo area.
Even so, it's in a quiet street so there's not too much noise (as possible as this is in Buenos Aires).
Andrea was a great host, she was in contact with us all the time and helped us whenever we needed it, even got us some nice snacks as a welcome pack.
I definitely recommend Andrea's flat, and we'll be there next time we're in Buenos Aires.
