Very spacious and unique -- an amazing blend of authentic/ancient, but with all the conveniences. Camila met us there and walked us through, explaining some of the traditional/historical features, while pointing out the free access to laundry facilities. There were phone charging ports in the nightstands, power converters in bureau drawers. All in a medieval fortress! Kitchen was well-appointed, and we enjoyed making our own espresso in the mornings.
Vicopisano is a lovely place to stay. Extremely picturesque and interesting to wander, very quiet and peaceful. It's also a great location for daytrips -- less than an hour to Florence, half an hour to Pisa and Lucca. We did a truffle-hunting outing in San Miniato (about half an hour away). Had planned to do a daytrip to Cinque Terre, but ended up with rental car problems and lost that day. Easy access to many other Tuscan hill towns.
The historical center of Vicopisano is small, but we very much enjoyed the restaurants, the panini shop, the pastry shop, the gelato shop. All of which are a short walk from the apartment. Likewise, we visited the Frantoia just outside Vicopisano, which has a shop with a lot of nice local products to buy.
This is a family business, and the family is very proud of their work, and treats renters as guests. They were tremendously helpful and kind when we had car problems. All in all -- a perfect stay. Would've liked to be here for 2 weeks, instead of our 5 nights :-)
