K West Spa is just a stone's throw from Westfield near Shepherds Bush. It may not have the most glamorous location, but its spa is a little hidden gem. The hotel is a glass box - walk through the bar and get a lift down to the subterranean spa, where you'll be given a robe to change into and sat in the waiting area. They have a specialised prenatal therapist - Lyudmila - who managed to mix a soft, reassuring manner with a seriously firm touch. Here, you get the choice of two Aromatherapy Associates oils that can be used in pregnancy - camomile and rose. My pick was rose.
