Population
Do you know the population of Italy? The population is right around 70,000,000. That is a lot of people! Not all of the 70 million people in Italy are alike, everyone has a different style in life so many people might have big magnificent houses when some people might have a house that just fits them, a bathroom, a kitchen, and rooms to fit them.
Go on the Home screen and the Work sited for great pictures. As you can see from these pictures, the houses that you see are really nice and big.
