Good question, bestbefore ... I too have been trying Marta for an age with no reply 
... both she and Maria appear to have disappeared. I do hope they'll make a return. I loved being under them!

Saw Marta last year on the fact she was praised so highly and I thought YMMV. Saw Maria as well as I left and she looks a lot of fun.
Found Marta a nice woman and very sensual but would not trek down there again for her unless passing, ill check if it was under 6 months ago and get a review up.
I found her a really nice person though.
Maybe they gone back home for a bit or are trying out a different part of the UK? I am saw some gents who are regulars will know, pretty sure they ran profiles on Vivastreet and Massageme - although such threads on Massageme seem to keep getting deleted or locked generally.
Edit: If they where local to me, that would be a whole different story and would likely have seen them multiple times now, build up trust and hopefully YMMV
