This 314-room downtown hotel is housed in a 1926 building that was the original corporate headquarters of Shell Oil Company. But it's not all about historic appeal here -- guests are greeted by the fantastic modern lobby, which features high ceilings, curved suede sofas, soft lighting, and a cool fireplace. Each room is outfitted with premium bedding, thick velvet drapes and flat-screen TVs. Gorgeous bathrooms feature marble and granite, and each has a separate walk-in shower and big soaking tub. There's no spa, but guests can access the 24-hour fitness center or hit up Houston's only rooftop pool and Jacuzzi for some sun and relaxation. The hotel also offers some great perks, including free shoe shines, free daily breakfast, and an evening reception with assorted beers and wines. Bedtime milk and cookies are also served -- a cute and comforting touch.
