Hi Colette
I like the sensible slow pace of 2 weeks and 2 bases.
Others can comment on Rome, but it makes sense and does not require Italian language skills.
Some thoughts for the other week:
- Amalfi Coast (specifically Ravello, but there are other places of charm). The whole coast is interesting, with stunning views, great food, famous historical sites. If wanting to explore them all, then Ravello isn't the best choice, as it is more isolated. However it's that relative isolation that I'm pitching as the appeal. There are formal & informal villa gardens to explore, a charming pedestrianised square in its element of a warm evening, views that are exceptional, walks varying from easy to strenuous (the tippett guide in the sunflower series is invaluable). Plus if you time it, a series of classical concerts. Overall though, it is the amazing sense of peace looking out over the seascape that can create a pure silence. Language again not a problem here
- Tuscan/Umbrian countryside - you've mentioned it, and like the Amalfi coast, it offers a lovely counterpoint to the hustle and bustle of Rome. Driving is definitely an option, but holidays can be planned around trains and buses (the inter-town ones being referred to as pullmans by the locals). Mostly the driving is easy, but going into/through towns can be a little stressful (good planning helps). Best to train from Rome to a suitable place to pick up a car & ideally arrange to drop the car off at your departure airport
