The principal difference between a 3- and 4-star hotel in Kazanskaya Khava will be the level of service and access to creature comforts. Three-star hotels are generally more wallet-friendly and provide the services and amenities you need to ensure your comfort, such as WiFi, breakfast and a gym. You can count on a little more at a 4-star hotel — think upscale furnishings, luxury toiletries and extras like on-site spa centers.
