Elemis Day Spa, London. Any recommendations?

[agentginger]

Hi, I've just joined mumsnet, and this is my first post. My partner is pregnant with our first child. We've recently had our 12 week scan, and i'd like to give her a spa treatment near xmas.
I googled and found Elemis Day spa in London do treatments for pregnant women. Does anyone here have experience of this and could offer an argument for/against it? Or do you have any alt recommendations for day spas in London for those with bump?
Thanks in advance
