Despite these snafus, we were happy at Sole di Sesta, mainly because we fell in love with Vanda and our cook, Delia. (To this day, we drool at the memory of Delia's zuccotto.) We had managed to find a villa that was fine but not spectacular, that suited many of our needs but not all. Which brings me to the all-important lesson eight: To get the perfect villa, book through a specialist (see "Wendy's Rolodex,"). Here's what I found when I accompanied two of them on their property inspections.

Maria Teresa Berdondini, owner of the agency Charming Italy, showed me a property called Villa Pecille that was precisely what I had sought from the start. A restored seventeenth-century farmhouse just outside Panzano—a better location than Gaiole—Villa Pecille is owned by the Fontodi winemaking family and sits on Chianti's famous Conca d'Oro, or Golden Slopes. There, I could have had both my exquisite hilltop views and a short walk into town. The property is divided into five unique "apartments" that hold from two guests (for twelve hundred dollars per week) to eight (for four thousand dollars). As I took stock of the toddler-friendly touches—safe staircases, windows that open only from the top, marble countertops with rounded rather than razor-sharp edges—not to mention the bath amenities, the satellite TV with four English-language channels, and a laundry room with multiple washers and dryers, I felt a sharp pang of regret.

But that was nothing like the chagrin I felt when I drove up to Ca di Pesa, also near Panzano, with Italy specialist Mara Solomon of Homebase Abroad. My first sight was of a wooden swing hanging from an oak tree and an ancient limonaia (like an orangery, but for lemons) turned children's playhouse. Ca di Pesa is a borgo (an entire medieval village) transformed into stylish accommodations for either ten, fourteen, or twenty-two. Even though it has everything a childless aesthete could want—including an elegant cantina (wine cellar) for dining by candlelight—it is also a parent's fantasy. There's an eighteenth-century rocking horse, a Ping-Pong table, a bocce court, a TV room with a video library of English-language children's classics, and three kids' bedrooms, each with a spectacular fresco covering all four walls and the ceiling (one of underwater sea creatures, one with circus acts, and one a jungle scene complete with a monkey, a snake, and a parrot perched above the doorway). How sad not to have either $11,300 (the low-season weekly rate for up to ten) or a bigger group to split it with. Honestly, had I known in advance that a place so simultaneously adult- and child-friendly existed, I would have scrounged up either more money or more people.

What distinguishes agents like Berdondini and Solomon from those at the villa-rental factories is not only that they have access to homes others don't, it's that they are friends with the owners. Which leads me to lesson nine: Use an agent who has a close relationship with the villa's owner, since it's the owner-agent bond that ensures a smooth stay and gets your special requests granted. It can even gain you entrée into the local culture, because the best rental agents select homes on the basis of the owners' and staffs' hospitable natures and their desire to be of service. In Europe, many owners live nearby and, if they sense interest from you, will reach out to welcome you to their home and region, perhaps inviting you for dinner or to their private winery. If you play your cards right, they could introduce you to people in the community. Which brings me to lesson ten: Interaction with the locals is, in the end, what makes a villa vacation most memorable. "People come back talking about the woman at the bakery in town who made a special cake for them or the local restaurant owner who taught them to cook in his kitchen," says Solomon. "They come back feeling that they've made friends with people in Italy." It's that unrivaled access to the local community—combined with a home base handpicked to suit your tastes in everything from decor and location to amenities and architecture—that turns an ordinary villa vacation into a magical one.
