yoga retreats for beginners

Hi,

I've just started learning Ashtanga and would really like to go on a week's retreat sometime in February or early March where I can get some qualified teaching, either one to one or in a similar level group, in a relaxed atmosphere. Ideally I'd like some sun, but will be travelling alone, so want somewhere where I'll feel comfortable as a single female traveller. Also, somewhere comfortable but not too expensive would be great. As would optional extras such as meditation / massages.

Any recommendations would be gratefully received!

Thanks,

Gin
