Unlike hotels or Airbnb, where you can book an extended stay, Couchsurfing is limited. Given that a host provides you free accommodation staying long is not an option. Hosts in Couchsurfing include in their profile the maximum number of stay they want to host. Most couch surfers live with the host for as long as three days. Going beyond the timeframe should be negotiable with the hosts. Couchsurfing is ideal for short stays. If you will visit a city for less than three days, Couchsurfing is a suitable option. Yet, when your trip extends beyond three days, you can find another option, like Airbnb.
