Berlin - The Wall city I loved Berlin and the history, the hop on hop off bus is a great way to see all of the sites. I went on a day trip to Sachsenhausen Concentration Camp which was very profound and thought provoking. The Wall was another tick off my list! Tip: stay close to the Alexanderplatz area it is the hub of the city. Instead of getting on the tourist hop on hop off bus use bus #100 as this is exactly the same as the HOHO bus and stops in all the same tourist attraction spots at a fraction of the cost and the locals also use this bus.
A definite must see city in my books!
