If you choose to book a stay at a 4-star hotel in Dupont Circle, you'll typically find plenty of amenities to ensure you're relaxed, such as a gym, pool and restaurant. You can look forward to excellent service and upscale surroundings. Pick a 5-star hotel and you'll have access to a few extra bells and whistles — think on-site spas, around-the-clock concierge and opulent turndown services. You're likely to get additional amenities and first-class services at a 5-star stay, though both are great options for luxury guests.
