Spanish courses (London)

Hello everyone, dear London community!

I hope any of you will be able to direct me to the right place: I am desperately looking for a Spanish language course which I would be able to attend, due to my work schedule, only at Sundays eve...
Quite hard, apparently nowhere it's possible.

But I trust my IN community!

Any great advice to let me come back to my previous amazing Spanish knowledge ???

Thanks in advance to the ones who will reply to me.

Good night everyone!
Antonella
