I am just finishing a six week trip in Spain and France. I have enjoyed visiting traditional Marriott properties in Madrid and Paris. I have also been happily introduced to AC Hotels in the Spanish cities of Burgos, Leon, Pamplona, Madrid, and Toledo. In the countryside (where Marriotts properties are not available), I have tried many different AirBnB properties. I would be interested in hearing your general thoughts on AirBnB in Europe. Pros, cons, experiences, etc.
