Claudia and Marco were our most gracious Airbnb hosts hands down. They went out of their way to accommodate our needs - my husband and I were both vegans and had early transfers and they packed vegan croissants and biscuits for us early in the morning. Their place is a few stops away from the Vatican but conveniently placed 5 minutes from metro and bus stops. Really.
I can't recommend them enough. They are truly superhosts. Claudia and Marco, grazie and hope to see you again soon!
