Liden & Denz is one of St Petersburg's oldest language schools, having opened in 1992. Now they have expanded into a large new centre not far from Gostiny Dvor (though the original centre off Ligovsky pr. also remains opens). Russian is taught mainly in groups of up to 10 people, though individual tuition is also available. Classrooms are bright and equipped with televisions and DVD players. There are computers with internet access for student use, plus wi-fi internet if you want to bring your own laptop.
