Trastevere, Rome, Italy
"When in Rome" might be an oft-quoted phrase, but visitors to the Eternal City don't always take its message to heart. And it's clear why: In this bustling metropolis where ancient ruins and Renaissance grandeur rub shoulders with fashion icons and modern architecture, it's difficult to actually take a moment and breathe all of it in the Italian way -- surrounded by friends and family with a glass of wine at hand. Life is meant to be savored, not rushed. Roman hoteliers, at least, understand this. And whether tucked away into courtyards or shimmering under a Roman sun, hotels in this European capital have created their own secret gardens perfect for a little R&R, Italian style. This leafy outdoor garden at the Donna Camilla Savelli -- a historical 17th century monastery converted into a 78-room boutique -- is a relaxing spot for summer breakfasts or evening cocktails. Its charming atmosphere speaks to the rest of the property, which features wood-beamed ceilings, arched hallways, marble floors, and antique-style furniture.
