The new JW Marriott in Houston is aiming to elevate the city's standards for luxury hotels. Guests who enter the hotel are now greeted by employees with iPads who check them in without a wait. The hotel has added Nespresso machines to each room. Meanwhile, the hotel will offer flat irons and Moroccan oil treatments. Natalie Wiseman, director of sales and marketing for the hotel, also noted that the hotel, which will open in August, will feature original artwork on each floor and in some rooms.
