We loved staying in Faena in Brigitte's apartment. A truly wonderful experience.
Brigitte was there at all times wanting to help and guide in all things Buenos Aires. She allowed an early check in and late check out which was appreciated.
A very beautiful apartment! A very beautiful hotel. I would not hesitate to recommend to anyone for a great people watching experience and height of decadence. You must have dinner in El Mercado and have at least a cocktail in the lounge bar.
If you are into people watching find a good couple of hours to just sit beside the pool!
