Hospitality Club: free accommodation around the world

What is the Hospitality Club?

Our aim is to bring people together - hosts and guests, travelers and locals. Thousands of Hospitality Club members around the world help each other when they are traveling - be it with a roof for the night or a guided tour through town. Joining is free, takes just a minute and everyone is welcome. Members can look at each other's profiles, send messages and post comments about their experience on the website.

The club is supported by volunteers who believe in one idea: by bringing travelers in touch with people in the place they visit, and by giving "locals" a chance to meet people from other cultures we can increase intercultural understanding and strengthen the peace on our planet.

Come onboard - join the largest online hospitality exchange organization! You will meet friendly people and find free accommodation when you travel to any corner of the world. There are no obligations (you do not have to host anyone at your home!), membership is free and we would love to have you in our world wide web of friendly people!
