If you decide to book a stay at a 4-star hotel in Kremlin, you'll usually find plenty of amenities to ensure you're relaxed, such as a gym, pool and restaurant. You can enjoy high-quality service and upscale surroundings. Opt for a 5-star hotel and you'll get a few more perks — think around-the-clock concierge, on-site spas and indulgent turndown services. You're likely to get more amenities and exclusive services at a 5-star retreat, but both are awesome options for luxury guests.
