Depending on your requirements, a good hotel costs more than 200 euros a night, while a cheap hotel costs 30 euros. If you eat bread and sausage, a meal costs 3 or 4 euros. If you eat a large steak or pork elbow (this is a German specialty, you must try it) and then have some beer, it may cost about 20 euros. The ideal state is to eat bread at noon, have a big meal at night, eat about 25 euros a day, and stay in hotels (including breakfast) for about 80 euros a night. Sometimes many hotels have special prices on weekends. 14 days to eat and live is about 1500 euros, and it is still expensive to take a taxi. It is recommended to take the subway as much as possible. The subway traffic in Germany is very developed, and the trains between cities are also very developed, such as ICE, IE, re and so on. , very convenient and fast. You will travel to many cities 14 days. This fare should still be quite high, and ice is also quite expensive. Generally, it takes tens of euros to get from one city to another, so I think you should prepare at least 500 euros for transportation. Therefore, if you stay alone for about 14 days, buy nothing and visit many cities, all the expenses of 2000 euros should be relatively comfortable. If two people go, the housing will be saved, and everyone's basic expenses will be less. I hope you have a wonderful trip!
