The big difference between a 3- and 4-star hotel in Kolokoltsevo will be the standard of service and availability of creature comforts. Three-star hotels are generally more affordable and provide the services and conveniences you need to ensure your comfort, such as breakfast, WiFi and a gym. You can look forward to a bit more at a 4-star hotel — think upmarket décor, luxury toiletries and extras like spa and wellness centers.
