Sara's place was well kept and was a great place to base ourselves, the accommodation had everything we needed, it was nice and clean, the view from the terrace outside was great to sit out on and watch the sun set with a glass or wine (or tea).
There is a supermarket around the corner, and a little further a coop, we used the coop, it was about a 5 - 10 minute walk, not too bad and the shop had plenty of things.
For getting in and out of Florence we advice the number 1 tram, things seem to have changed, and the maps we used with buses on didn't seem to be up to date, which as confusing at first, and always as with anywhere in Italy - always buy a ticket and always validate it!!
Would happily come back again.
