My husband Joe and I have been living in Italy off and on since May, 2016.  For the first 14 months, it was more off than on.  For those first 14 months, we were here in Italy for a total of 219 days.  Only once in that time did we come “close” to hitting the 90 in 180 days rule, and when we flew out through Germany on the 89th day the German immigration officer perused my passport for a good 3 minutes before letting me through!  It felt like 30!
