If you choose to vacation at a 4-star hotel in Chiyoda, you'll usually find plenty of amenities to ensure you're relaxed, such as a pool, gym and restaurant. You can look forward to top-quality service and upscale surroundings. Go for a 5-star hotel and you'll get a few more perks — think on-site spas, around-the-clock concierge and nightly turndown services. You'll most likely get extra amenities and first-class services at a 5-star getaway, but both are superb options for luxury travelers.
