A host family homestay location is of great importance. Your homestay will be more popular, if it is located close to a university, or public transport.
If not, it’s worth offering that disused bicycle, as part of your homestay arrangement. If you’re already commuting to the city by car, perhaps you could consider offering a lift into that central location?
Whatever your location, consider these points in writing your host description and, tackle any potential ‘deal breakers’ before they break the deal.
