Is ten nights to long to spend in the Siena Area? We are staying in a hotel inside the 'walls' - Palazza Ravizza - any one stayed there? How central is this? Have been to Siena 10 years ago but only for half a day - this time want to get a 'feel' for the region. We come from a high quality wine producing area and are keen to sample local wine - prefer smaller wineries if any one has experienced!
