The charm of travelling deals with change: leaving the routines and discovering new places, where people can find new friends, new food, new customs. But sometimes, hotels seem to be old and known: as airports, hotels are almost similar in every part of the world. Generally –because there are exceptions– hotels are cold and impersonal. Some time ago, many people started to look for a more personal experience in lodgings which would allow them to become more acquainted with the customs of the place they visit. When such people came across those who were searching for cheaper lodgings, a new way of travelling arose: the house exchange.
