If you decide to vacation at a 4-star hotel in Ust-Sema, you'll typically find lots of amenities to make sure you're comfortable, such as a pool, gym and restaurant. You can look forward to top-quality service and upmarket surroundings. Opt for a 5-star hotel and you'll have access to a few more bells and whistles — think on-site spas, concierge assistance and nightly turndown services. You'll most likely get additional amenities and premium services at a 5-star retreat, but both are fabulous options for luxury guests.
