English classes in small groups with native speaker

Hi I'm Livia. I'm from the USA and have been living in Spain teaching English for the past 4 years. This year I am offering small group classes of 3 to 4 students in my house, which is near the Atocha Renfe station. The groups will be formed based on the level of the students. I teach A1-B2 levels and can prepare for the First Certificiate.  I charge 12 euros an hour per student if it is a group setting, or 15-20 euros an hour if it is a one-on-one class.
