The biggest difference between a 3- and 4-star hotel in Podolsk will be the quality of service and access to creature comforts. Three-star hotels are generally more wallet-friendly and come with the amenities and services required to ensure your comfort, such as a gym, WiFi and breakfast. You can count on a little more at a 4-star hotel — think upscale furnishings, deluxe bathroom products and perks like on-site spas.
