It's hard to find hotels that offer everything you need: comfort, space, and a good location. Luckily, in Florence, you'll find that many hotels within the city center offer great rooms options for those traveling with children or families. It's always stressful when you are planning on taking a trip with little ones in tow, but when you choose the right hotel, it's amazing how much better your trip can go.
Try Antica Torre, an old tower converted into a classy yet comfortable hotel with charm. You kids will love the fact that there is some history behind the place that they are staying, and you'll love the spacious rooms and the chance to kick back and relax after a long day of sight-seeing.
Also look into the Hotel Rivoli. Not far from the train station, and only about a ten-minute walk from the Duomo, the Rivoli offers a great, friendly staff who wants to serve you. If you have any questions about the city or need anything, they can find you what you need. For budgeters, consider Hotel Casci--a family-run business dedicated to offering you a pleasant and clean experience for a more than fair price. Florence offers guests the trip of a lifetime if they know where to look.
