W St. Petersburg features a more modern and fun experience than competing chain hotels nearby. Interiors are chic with a funky flair, featuring rich colors of purple, blue, and red mixed with dark furniture and lighter shades on the walls. Decor is fun, with a European Russian twist, including fancy lighting throughout, funky mirrors, and an interesting collection of ornate art pieces on display shelves. The Living Room is an eclectic space with a constantly changing atmosphere, from tea in the afternoon with board games and books by the fireplace to casual evening drinks leading into party-fueled nights led by resident DJs. Both the Panoramic Wine Terrace and Cococo are slick and elegant with richly-colored lavish decor. Bliss Spa offers a memorable experience with luxurious treatment rooms, blues tunes playing in the background, and a free sparkling wine and brownie buffet. The hotel has adopted the chain's famous Whatever/Whenever strategy, where staff will do their best to please any sort of guest request. Business travelers and couples looking to explore the city's historical sites are the most frequent visitors to this hotel, since there are limited features available for family travelers.
