This appeared a short while ago on the UK Punting Abroad section with respect to the Placer Madrid place, linked to above. Seems to still be an excellent choice.
”I'd reviewed 3 SPs, two of whom I saw again last week, Rubi and Mariana.
Both top rated, Rubi, CIM included in standard rate, very pretty, lovely way with her. anal and CIM in Marianas rate.
But my favourite was Becky.
Still best value in Madrid/ Spain IMHO, but you still need to read the reviews on the Madrid Web site.”
