What a gem. The photos don't do this stunning penthouse apartment justice.

The staff are so attentive, and the space so luxurious and the location so good that you'll wonder why you bothered with hotels before. And, if you're a large group (there were five of us) like we were, the rates are half what you would pay in a decent hotel. Jennifer was away in Budapest when we stayed, but household manager stocked the apartment with groceries from a great local deli before we arrived, put out fresh flowers in all the living spaces, insisted on helping prepare breakfast, and made up the rooms every day. She even offered to do laundry, etc, if we needed.

The service was fabulous, but the apartment itself is the rock star: stepping off the busy sidewalk through an elegant private foyer, you ascend a spiral staircase, in marble, to arrive in the double volume living area, with open plan kitchen, dining room and lounge all bathed in light from the full length floor to ceiling windows. The entire apartment is tastefully decorated, with a fantastic kitchen, equipped for gourmet cooking / entertaining. The four bedrooms are quirky in design / layout, but are well proportioned and beautifully appointed. You should, however, be aware that the bunk room is much smaller than the others (and smaller than it appears in the photos) and is only really appropriate for one person, or for kids.

The roof-top terrace and cupola lounge are fantastic for entertaining or just for chilling. The master bedroom opens out onto the terrace.

I travel to Buenos Aires once per year, and will definitely stay here again.
