Dear Sam,

I hope everything is going well in your house (or going well at home). At the moment I am in Pisa. We started our travel in at the border between France and Italy. Our first stop was Sanremo where we enjoyed a wonderful sunny day. Later we went to Genova and we did a tour around 3 big palaces. Our next stop was one a place named "Cinque Terre" they are 5 small villages on the seaside (or coast) surrounded by cliffs. The unique only way to go from one to the other is by walking or by train. I was sad because we couldn't spend more time in this place, the food there is really nice. Tomorrow we are going to go to Florence and I hope we have enough time to visit all the monuments. 

On Monday we are going flight to fly back home (or we are taking a flight back home), once we are there I will call you to explain tell you all the details of our trip.

Regards

Inma

Very good Inma. My corrections are in red and my suggestions to sound more natural are in blue/grey.
