Good Mandarin Course needed (Beijing)

Hi Everyone,
I had been studying Mandarin for 14months in the UK before I arrived in Beijing. I would like to continue with this over here - doing a short-term course, maybe 12weeks Protected content . I've looked at several sights on the internet and will be seeing 2 schools early next week.
However, I was wondering if any of you can recommend a Mandarin course which you have taken yourself or which is recommended by anyone you know.
Any help would be appreciated as I hope to start a course in the next couple of weeks.

Regards,
Aey
