we will be staying at Borgo Di Carpiano in Gubbio this May. We are undecided on how many nights to stay here. It seems from this location, there are many feasible day trips to Assisi, Urbino, Orvieto, Todi, Trasiimeno lake... I would also like to see Montalcino, Monteplciano and Sienna. Do we need a second base for instance in Sienna to visit these places or are they doable day trips from Gubbio. The more I read, the more confused I become so any help is appreciated. thank you.
