We recommend Pierpaulo's apartment. It is bright, comfortable and spacious as italian apartments go. We were three adult Canadians who are used to a lot of space and this apartment met our needs. It is well situated, half a block from the Ponte Vecchio and within walking distance of all the major tourist sights. Pierpaolo's neighbour Jun lives right next door and was able to help us with information and any requests we had. He even took us around for a short walk of the neighbourhood and showed us the best restaurant and gelato place. Pierpaolo himself showed up when we wanted to have the heating turned on. We would stay there again if we returned to Florence.
