Always wanted to visit and now i can finally cross this one off my list.
Great city immense history, a little like London and totally felt at home. Lots to see and do the most important for me was The Reichstag. In fact this needs to be booked well in advance, and as i love architecture i knew i would adore this structure i booked two visits. One for sunset and one for early morning in the bid to get it empty.
Brilliant building, a little military in passing through security and entering the building etc but obviously as its a government building its a must. You must have your passport or some form of photo ID without that you cannot enter. You can roam at your leisure once inside go out on the balcony which shows off immense views over Berlin - loved every minute and we had a superb sunset.
Next is the Jewish Museum. Sad eery and so intense, i left feeling so sad i can't even tell you. But its a must if you visit the city. If you have a gold card (3 days travel pass) you do get a lot of discounts entering most sites so i would suggest getting one. It acts like a hop on and hop off for all the transport. Its your mini passport around the city and we used it from 6am through to gone midnight. We must have walked in excess of 35 miles around the city the 4 days we were there.
There are may rooftops you an visit most bars have an external terrace and you can also attend the Park Inn for €4 and visit the top fab views.
