The biggest difference between a 3- and 4-star hotel in Kovylka will be the quality of service and access to creature comforts. Three-star hotels are typically more affordable and provide the services and conveniences required to be comfy, such as a gym, WiFi and breakfast. You can look forward to a bit more at a 4-star hotel — think upmarket interiors, luxury toiletries and perks like on-site spas.
