My wife and I are active adults in our mid 60's celebrating our 45th anniversary next year. We have friends that have visited this part of Italy and used Sienna as a base of operations for two weeks. This appeals to us as we are capable of using public transportation and typically stay in AirBnB's. I have read that Lucca is an equal choice to use as a base.
We enjoy hiking, architecture, some history, wine, and the countryside. Morning coffee at local shops is fabulous. At this point, I think I wish to find out if this is reasonable plan and what are some of the regions we can easily get to for day trips from Sienna. We also hope to possible get to the coast for a night or two if that works.
Looking for broad ideas now that we can tighten down.
