Corsica in winter

Planning 6 days solo in Corsica in late January: • Calvi – 3 nights • Expecting it to be quiet. citadel walks, coastal walks, Balagne village drives, long meals • Mountain farm stay – 2 nights • With a car • Intentionally slow: walks, cooking, reading, enjoying some warmth

I know it’s off-season — not expecting beaches but am looking for sun

•	Is Calvi a decent winter base if you have a car?
•	Are Balagne villages still worth visiting in January?
•	Any winter-specific pitfalls to plan for?

I’m a little hesitant as I’ve never heard of the island, and don’t want it to be completely in “off” mode. Any tips?
