Interesting and noteworthy posting by Peter.
We can add a few pointers for
The Netherlands and
Spain . The former because one of us is Dutch and we have both lived in The Netherlands. For Spain because we have done a lot of research into where to purchase a Spanish Casa Rural and presently run one.
In The Netherlands the B&B industry is regulated in many ways. (far too complicated to post here). Because of this it is
quite difficult to open a B&B in a normal house. However if you want to find one then either approach the local VVV (tourist information office) in the area you want to stay or visit the web site for the VVV of the area. Breakfasts will consist of things like bread, cheese coffee etc. Usually there is no evening meal provided, nether are alcoholic drinks. Both of these are usually available locally. The local authority will be the controlling body for the B&B.
In Spain the word B&B is not commonly used expression. Here you best do a web search for a
Casa Rural . These are usually, but not 100% so, in small towns or villages. Some communities they have to be registered with the controlling body others not. Usually can find Casa Rurals though the website or tourism offices of the local community. However there is one good web site that lists Casa Rurals all over Spain. It is called
Toprural (do a Google search for it). The owner of the Casa has to pay to be listed but there are reviews by guests of the house.
Breakfasts can vary, but usually consists of local produce, bread, coffee etc.
Other than Casa Rurals you can stay at either
Rectorals (large homes formally lived in by Priests) or
Pazo (large country homes of Nobles; formally). Both of these classes of accommodation are grander than a Casa Rural, so expect to pay a premium for the nights stay. The controlling body will inspect the house several times a year for hygiene problems. Classes of Casa Rurals will vary with different communities.
We hope you find this information of use and hopefully others will have an inside to other countries.
