We arrived in Florence by train (from Venice). The apartment is only 10-15mins walk from the station and in a great central location just 2 minutes from the Ponte Vecchio, the Uffizi Gallery and the Piazza della Signoria.
Bruno's son, Luca, kindly met us at the apartment at a time suitable to us. Luca was very friendly and gave us some great tips on local restaurants and where to find the best supermarket if we wanted to cater for ourselves (just over the Ponte Vecchio). We tried two of the restaurants (Trattoria ZàZà, Piazza del Mercato Centrale and Tamerò Pasta Bar, Piazza Santo Spirito) and had great food at both!! (Thanks Luca).
The apartment is bright and airy, clean and comfortable and had everything we needed. The city centre location does mean there are no views from the windows (straight into another building) and can be noisy at night. But if you want quiet then you will probably have to find somewhere away from the city centre.
As well as the standard sights around Florence we also visited Siena (beautiful Duomo, well worth the full tour), Pisa (just to see the tower) and had a fabulous day in the Tuscan country side with Tuscany Bike Tours (http://www.tuscany-biketours.com/) - really highly recommended. The Galileo museum in Florence is also worth a visit for somewhere different and no queues :)
We really enjoyed our stay in Florence and would recommend the apartment to anyone who wants a central location.
