We were communicating with Michele well ahead of our trip and he gave us valuable advise for our journey to Florence via Pisa.
Michele met us at the apartment and after showing us around the appt, took us around the neighbourhood for quick orientation. He explained the city map and recommended what to do during our 2 day stay….hence we utilised our time very well.
Our 16year old absolutely loved the apartment for its rustic charm and so did we. Two bedrooms meant 4 of us were very comfortable and there was enough privacy for us.
Trattoria round the corner, I can't remember name of is excellent, try get the table outside. Inside is not bad either, we had to move inside as it started to rain.
Square near the appt has plenty of eating options. Be warned that its almost impossible to find even a snack bar on this side of the river after 10pm!

Ok tips in terms of travel to and fro from train station, if you are travelling light you could walk to the apartment, bus D bring you to the doorstep so is the other option and you can get it from station exit and it has a 20-30minute frequency. But as we were 4 and had been around Pisa, we took a taxi that cost 15euros.
Pisa to Florence is easy, bus or train, under an hour and costs about 6-15 euros on bus/train. We took a bus from the airport. Left luggage at the airport, took a bus to Pisa, did town square, back to airport and then a bus to Florence. 4 hrs were enough for the same.
From Michele's appt in Florence, everything is walking distance. We walked to Accademia, good 30 minute walk crossing key monuments and busy but gorgeous streets. Uffizi is across the Ponte vecchio which is a 10minute walk.
Handy tip, first sunday of each month is free entry to all museums and most monuments. Kids under 15 are generally free in most places and public transport.

All in all, recommend Florence, recommend Michele and his flat. Thank you Michele!
