I may have the opportunity to visit someone who is planning to live in Sardinia starting this fall. If I did visit say in the spring 2024 and only stay the maximum allowed 90 days my questions are the following.
Are the 90 days rules for per calendar year and from the time you visit?
If I decided to visit for the next 5 years, are there any restrictions if I would choose to do this?
Is the rules based on visiting within 365 days or is it based on a calendar year from Jan to Dec?
Thank you for your comments.
