Ciao Gabriele!
I can understand your concern about being able to come to Ireland at this stage.
All visitors
from any country are required to self-isolate for 14 days, avoiding contact with other people on the island.
I would also like to share the Farnesina website "
Viaggiare Sicuri", where you can find out the measures taken at the moment for visitors from other countries. Please keep in mind, as noted also on the Farnesina's website, that the measures can change any day, that's why it is important to check updates very frequently and stay in touch with the airline company, tour operator, and facilities booked (if any).
On the Viaggiare Sicuri page, you can also find links to the calendar of the
roadmap for reopening society and business, followed by the Irish government and in particular the page with advice for
traveling during this Covid-19 period. Here you have information on what to do when arriving in Ireland.
I hope I helped you to have a clearer picture so that you and your group of friends can decide what is best.
