When stuck in Termini Station and looking for things to do, I suggest popping in here for a book.
An excellent selection of books for readers of any language and you can easily find something to occupy your time while waiting for your train.
With two floors and lots to peruse, don't get too wrapped up or you'll miss the train you're here to catch.
You won't find comfy chairs or places to sit while browsing, and the aisles can be tight for those toting luggage, but those negatives didn't detract enough to dissuade me from spending time here.
Prices are full retail so there are not a lot of bargains to be found, but when killing time in Termini Station I'd be hard pressed for a better way to do so. read more
