We stayed in the Virginia apartment for a week, using Pistoia as our base for day trips to Florence (30 mins), Pisa (45 mins) San Gimignano (1 hour), Vinci and various other parts of Tuscany.
Couldn't ask for a better appointed apartment - all facilities are on hand and Titti provides a great welcome. You're also right next to the fresh food market stalls of Pistoia - and the restuarants, cafes and old town square (a hidden gem).
Not staying in bustling Florence was a real bonus - we were able to visit the city easily, but escape to a more sedate 'home' location.
I highly recommend - you won't be sorry!
