Rome — High Holy Day recommendation?

Hello fellow M.O.T.s,

This is a long shot, and apologies if these types of posts aren’t allowed. I’ll be in Italy this fall, and Yom Kippur falls in the middle of my trip. I’m wondering if I can find a good shul to spend the day.

I was raised conservative/Ashkenazi minhag, but am open to going anywhere where a secular American tourist won’t stick out like a sore thumb (if that’s even possible).

Also, would I have to contact a shul ahead of time?

Any takers? Thanks!
