In the Tuscan hills overlooking Florence sounds like an amazing place to celebrate the New Year... and you'd be right! Lucia is a wonderful host, as is her family, and their house on the hillside looks through the olive trees to the Duomo and history of Art and culture beyond. If you don't rent a car (we didn't) walking to and from the Tram can be challenging: it's about 1 1/2 kilometers. You can easily catch a taxi there from the city center (about 15-20 euro) but you have to call for a cab to get back to Florence if you don't want to walk (and don't have a car). In the spring or summer it would be a lovely walk to the Tram, but in the winter, it was quite cold. Fortunately Lucia and her family were always ready to help with a phone call or even a ride when necessary. Lucia went above and beyond being a gracious host in her help and kindness.
If you have a car, there is plenty of parking (unlike in the city) and the house is roomy and has all the amenities you will likely need. We stayed in after New Years and cooked and relaxed;it was wonderful.
There is a large supermarket nearby with, food, wine, electronics, and even clothing and boutiques inside!
The tram is very modern and clean and takes you right down to the heart of Florence where you can walk and/or cab to all of the fantastic sites.
We can't say enough nice things about Lucia and her family, so we'll just say grazie mille! And we hope we can come again soon.
