I love a good penthouse... But, really who doesn't. The glamour of saying 'penthouse', makes the approach exciting, plus you know the hotel dumped a ton of design resources into it, so it should look great.  The Thompson Penthouse at 6 Columbus absolutely does!

I love an open loft - it's so romantic and exciting, very one-with-the-city.

As you saw in 10 Home Essentials, I think a good geometric rug is one of them.  This one sings, with an interesting pattern, but the same good background colors. Pictures via.
