Let's cut to the basics: When it comes to a great hotel stay, the key is the bed. Whether a hotel guest is looking for a good night's sleep or just a good time, it all comes down to the sleeping accommodations. And the Westin's "heavenly bed" mattress is getting rave reviews. According to a review posted on Travelocity by one Laura K., "You will be in heaven in these beds." Laura loved the mattress so much, she went and bought one. Now she can feel like a Westin guest all the time. Beyond the bed, the rooms are big, the bathtub inviting, the coffeemaker stocked with Starbucks. The hotel itself is situated in a historic Cupples Station warehouse near Busch Stadium. Close by are the federal courthouse, the Gateway Arch and a MetroLink stop. But even as you're seeing the sights, taking in a Rams game, spending a night on the town or enjoying a relaxing sojourn in the hotel's mini-spa, bear in mind that the best part of the stay awaits you back in your room.
