Travellers can look for hosts by location, and hosts can find travellers whom have stated their plans to travel to their area. Hosts also list references (recommendations from previous guests), which helps travellers in deciding whether or not a host is reliable. When a traveller applies to stay at a host's place, the host then reviews the traveller's profile and either accepts or rejects the application. If the host says yes, the two users exchange phone numbers and contact each other prior to the meeting.
