One of the most beatiful cities in Europe is Prague. There are a lot of cheap flights to get there from every countries here, and you must spent no more than 2 or 3 hours to get there.
When you arrive, you realize you have been transported to the Medieval Centuries. The houses, the bridges, the Cathedral...all city, is so beatiful!!!
One of the things I really enjoied was the meal, and of couse beer. Chequia is a cheap country, you can have a Kings's meal for no more than 15$.
I also enjoied visiting the city by tram, it's very cheap (about 50c per travel) and it's arrives every place in city.
To go up top the towers was also and exciting and recommended thing to do there. From the top of the clock's Tower you have the most beatiful look of the city.
