If you decide to spend your vacation at a 4-star hotel in Sosnovka, you'll usually find plenty of amenities to make sure you're relaxed, such as a pool, restaurant and gym. You can enjoy top-quality service and upmarket surroundings. Opt for a 5-star hotel and you'll have access to a few more perks — think on-site spas, around-the-clock concierge and opulent turndown services. You'll most likely get more amenities and first-rate services at a 5-star retreat, but both are awesome options for luxury guests.
