St Stephen's Basilica is the largest church in Budapest. It was built in Neo-classicist style and has a capacity of up to 8,500 people. Its most noted relic is the mummified right hand of Stephen I, Hungary's first king, who among others converted Hungarians to Christianity. The adjacent square is home to several markets throughout the year and is lined by terraces of trendy bars and cafés.

Berlin is a vast city with not one, but several centres that come in their distinct and varied flavours of cool. The fastest and most time efficient way to hit all the main attractions is to get on one of those hop-on hop-off buses. You can get a 24- or 48-hour ticket, as well as an option to upgrade to a river cruise boat. Buses run every 10–15 minutes. Of course, you get audio commentary in multiple languages, plus a kids' channel.

Checkpoint Charlie, the most famous of the inner-German border crossing points and a name known the world over, was where Allied border guards would register members of the American, English and French Armed Forces (and their families) before they visited East Berlin. The "Wall Museum – Museum House at Checkpoint Charlie” is right next to this major tourist spot. The museum displays an incredible number of the original means and tools that people used in their escape out of the GDR: from the hot-air balloon to a mini-submarine, plus plenty of real and fake travel documents.
