Its big, its modern, it’s a Sheraton. It also had a multimillion-pound re-design in 2012, and stocks 54 gins (and organizes gin tastings) in One Square, the sleek new bar and restaurant. The facelift went a long way to dispelling the preconceptions that can plague a large chain. Of course, there are those who feel more at home with a familiar brand, but for those who might sniff at a Sheraton signature Sweet Sleeper bed, all I have to say is: it's a giant marshmallow of a mattress and one of the best night's sleep I've had in a long while. And then there's the spa, One Spa. The open-air rooftop hydrotherapy pool is still a winner,, as is the Roman-style thermal suite with its sauna, steam room, tropical showers, hammam, and tepidarium. The sleek new lobby has a communications hub with free Wi–Fi and PCs, while the Club Floor offers all those important little extras for business travellers, such as complimentary aperitifs and canapés at cocktail hour. The staff are as slick and professional as you'd expect in the Sheraton's UK flagship—especially the bartenders, whose knowledge of gin is encyclopedic.
