Leisure The elegance and style of the Sofitel Heathrow works its way through into the venue’s leisure facilities too. There is a spa with five treatment rooms, a relaxation room and a hydro suite with steam room, sauna and vitality pool. If you are looking to do something a little more active you can make the most of the gym which is open 24 hours-a-day. The spa is open only to adults over the age of 16.
