We have reservations pending and need help. We found nice sounding hotel (Arcobaleno) outside Siena "25 minute " walk to Piazza. My guess is the walk is uphill. Does anyone have experience with the walk (safety, curvy roads, traffic, etc). Reviews for hotels inside Siena walls seem mixed, and hotels are more expensive. We have 2 children (10 & 12) who are great hikers. Time might be a factor, and darkness at night after dinner in town. Dates - late March.
