Wow, what a terrific apartment. We were 2 families - 4 adults and 4 children all-up (all children under 12 years) and it was more than enough space for us. Valerio is a superb host and it was a treat to stay in this historic place. It was actually bigger and better than I had expected too. It is also very central to all of the historic sites in Rome - most things were within 10mins walk, with the Vatican a little further (we used the hop-on hop-off bus but probably could have saved the money!).
