This site looks like a mix of masseuses that are on various other sites, independently and agency, I am sure some have been reviews on UKP including: Simona and Bella.
They charge £70 for 1 hour outcall but 'Price does not include any travel expenses' (some agencies also charge more depending on what zone you are in).
but off the bat they are £10 over what other agencies charge for 1 hour basic...
