Well, that's interesting. It seems like since I posted they above, Villa Balquisse has updated its website

It seems that Villa Sharba is marketed separately (http://www.shaba-bali.com/) from a link from the main site - although in reality it's on the same site as Villa Balquisse

What you will see is a spa menu and pricelist now:

There's a PDF accessible on this page: http://www.shaba-bali.com/henna_spa.php

Hope that's of help to at least some people. I have to say, the next time we go to Bali, we'd be VERY tempted to stay here as it's stunning (although it's not on the beach, which detracts slightly....)
