Rome's enchanting Quartiere Coppede.

Most people who come to Rome for its fantastic architecture enjoy its Classical, Renaissance, and Baroque masterpieces.

But there's a magical, architectural wonderland in Rome that most visitors know nothing about. It's a little off the beaten path -- a short stroll from the Villa Borghese -- near the Piazza Buenos Aires. Called the Quartiere Coppede, it was built between 1919 and 1926 by Florentine architect Gino Coppede in the Italian Art Nouveau or Liberty style.

London Hidden Treasure: Kensington Roof Gardens

One of London's best kept secrets is the Kensington Roof Gardens. Still known to Londoners as Derry and Tom's, the gardens were laid out atop a department store in the mid-1930s. The gardens -- which cover 1-½ acres -- comprise the largest roof garden in Europe.

There are Spanish (based on the Alhambra in Granada), English Woodland -- with 30 species of trees -- and Tudor style gardens. And now, a hot nightclub and award-winning restaurant.

Abercrombie & Kent tours for women.

Abercrombie & Kent sent me an email today announcing their "women-only journeys."

To be honest, we've never been fans of women's tours. The pioneers in this field were notoriously unprofessional. Travelers who'd paid in full for their trips would often learn a couple of weeks before departure that they'd need to pay a "supplement" because too few people had signed up for their tour. And the standard of accommodation was not commensurate with the price.

But we're all for A&K entering the market. So many single women want to travel but don't want to go it alone and don't want to feel like fifth wheels in a world of couples.
