Language Trip to Russia-recommandations needed (Zurich)

Dear all,
I am learning Russian for ca Protected content now and was wondering if anyone could recommand a language trip or school in Russia. Have you learned Russian for Protected content in Russia and had a good experience? Can you recommand an organisation (including a room/hotel for the stay). Just to improve the language during a stay was my idea. But since I plan going alone I would prefer good and safe recommandations.
Thanks Alessandra
