Our trip to Lisbon to see my son who is studying at Lisbon University as an exchange student provided our first stop in Berlin. Guillaume provided our accommodation in Berlin. It was the first time we had used Airbnb and I have to say it was a delight to have selected Guillaume's home. His instructions to get to his place and help for what to do in Berlin was a great, as it was our first time in Berlin. I would recommend Guillaume's place to anyone who wishes to travel to Berlin and need a place to stay.
