Members offer anything from a guest bedroom to a sofa, to a foam mattress for a sleeping bag. The rest is up to you.
At the time of the visit you may choose to offer airport pick-up, breakfast, tours of gay and/or tourist spots or whatever else a good host may think of - depending on your possibilities. Think how you would like to be received.
Each member decides how many guests he/she can receive and when. Nevertheless, this is a hospitality exchange and, therefore, not for those who aren't capable of, or interested in, receiving other members.
Don't forget that both hosts and guests benefit from each visit! Our hosts have their house rules, as we have ours, and appreciate when they are respected.
Because the hospitality is free, a token gift or a dinner invitation for the hosts might be appreciated.
