I used this company to book my first German Beginners evening course in January. The website was easy to find a course near me. I am now on week 8 and the teach is really nice and the rest of the students are really friendly. So I would really recommend their Brighton school. I think I will be doing the next course. Or booking a language holiday this summer.
The course is 8 people and the teacher is German but lives in the UK and she talks half in German and half in English. We all were given a very high quality text book and can keep it afterwards. We are about half way though it and have a test next week.
I have not had any problems with Cactus Language and they helped me decided which level I should start at and I think £15 a week is not too bad, for 10 weeks.
