We had a wonderful citytrip with Fabio's place in the absolute center (50 meters from Pantheon!!) in Rome. His hospitality and friendliness made our stay perfect. We deliberately didn't visit the Vatican to have a good reason to revisit Fabio in the future.
A tip for all other guests: don't order an Americano coffee at breakfast in the presence of Fabio; as a true Italian, he will very dissapointed ;-)
