Savings: Home accommodation via Couchsurfing, for example, is free and Airbnb lodging is often less expensive than hotels. Choosing home accommodation will save several hundred euros from your travel budget, which you can then use for other experiences.
Remember this: Staying with a stranger may seem scary at first and you may have questions about the condition of the home. However, accommodation services allow you to learn about the hosts by reading comments and reviews from other travellers so you can find a suitable place to stay.
Reducing your carbon footprint: Staying with locals for five days a year instead of a hotel reduces your carbon footprint by 1%. Emissions are lower as a result of the decreased need to build new hotels and other accommodation.
