You should check the Council of Europe bodies dedicated to Roma (https://www.coe.int/en/web/portal/roma) as well as the country-specific reports by the Advisory Committee for the Framework Convention for the Protection of National Minorities (https://www.coe.int/en/web/minorities/country-specific-monitoring)
