If you choose to vacation at a 4-star hotel in Euston, you'll typically find lots of amenities to keep you comfortable, such as a pool, restaurant and gym. You can experience top-quality service and upscale surroundings. Go for a 5-star hotel and you'll have access to a few more bells and whistles — think on-site spas, concierge assistance and indulgent turndown services. You'll most likely get extra amenities and first-class services at a 5-star getaway, but both are great options for luxury guests.
