The hotel offered a deal if you book directly with them and mention the discount code EMMA&ALASTAIR.
Their prices are:
-85 euros standard room per night + 2 euro tax/day/person
-100 euros superior room per night + 2 euro tax/day/person
They don't have online booking on their site, so you'd have to email them at reception@anuscapalacehotel.it, mentioning the room type you want to book, for many persons, the dates and, of course, the discount code.
Bring your swimsuit, they have a pool:)
