Travel Accommodation
Postado por Frank (confidential) em Alemanha forum
Which type of accommodation you choose depends on your personal preferences as much as on local availability.
You can use a cheaper hotel (some cost as little as €40/night, but you get what you pay for), backpacker hostel or family B&B (which cost slightly less than cheap hotels) or AirBNB or youth hostels (which have an age limit only in Bavaria, as far as I know) or Couchsufing, which is completely free.
Not all of them are available everywhere, and costs vary. So check relevant listings and decide individually for each place you visit!
