http://www.ie.edu/ ESADE and IESE are the other two better ones.
One of them is often listed in european rankings occupying 3rd (After Fontaineblau and London School of Economics (¿or London Bussiness School?) to 10th position depending on the parameters considered.
http://www.esade.es/ http://www.iese.edu/ The one I selected (ICADE) is possibly the fourth best one, but I didn't want to study a Master in Financial Management (offered by I. de Empresa) but a Master in Finance - different programs. That's why.
