I went to Florence with the family in 2007 and had a great time. Here are the notes I made; unfortunately the delicious bookmarks have gone away.
Things To Do
Art, Architecture, Gardens, Food & Drink.
The centre of Florence is the Piazza del Duomo, the location of the famous Duomo and its bell tower, the Campanile. To the south of the Duomo is the Uffizi and the Bargello (part of the eastern district in the Rough Guide). They are two of the finest art galleries in Europe; the latter having a fine sculpture collection. Tickets for Florentine Museums can be booked online. It is next door to the Pallazo Vecchio, the republican town hall.
North of the Duomo is the Palazzo Medici-Riccardi and the Giardino dei Semplici (translated by Google). The latter has restricted opening times and at the backend of the week during the summer is open mornings only ’till 13:00.
On the other side of the river, there is another Garden, the Giardino Boboli as well as some more fine Palaces and the Plazza Santo Spirito, which has is surrounded by Cafes & Bars. The Modern Art Gallery is at the Pitti Palace in the Oltrarno.
