A very nice and calm place to stay after long days in Rome.
Please note (I didn't while scanning the description on airbnb :) ) that Villa Letizia is a religious institution initially created for pilligrims. In my opinion, it adds extra charme and tranquillity to the common ambiance but if for sole reasons you don't fancy sleeping under a crucifixion and staying in a place entirely run by church workers, take it into account.
With that said, I thank Villa and it's people for my very peacefull rest in its walls.
p.s. Breakfasts are good, especially croissants!
