"This museum takes you beneath the Trevi district, through an intricate maze of ancient vestiges to the archaeological ruins of Vicus Caprarius (which roughly translates to “City of Water”), an old Roman apartment complex dating back to the first-century A.D.. You get to see first-hand how the rich Romans lived, using their very own aqueduct–the same one that feeds the Trevi fountain–for their running water. The entrance is unassuming, and if you hadn’t been told it was there it would be easy to walk right past. There’s a fairly comprehensive website but all bookings are made (and confirmed) via a Whatsapp chat. Skip the guided tour—there were 8 of us in the tour group, but we shared the same (small) space with self-guided individuals, many of whom had just showed up and booked on the day. If you're keen on a post-museum cocktail, head upstairs to Harry's Bar." - Katie Parla, Maresa Manara
