The key difference between a 3- and 4-star hotel in Koreatown will be the level of service and access to creature comforts. Three-star hotels are generally more affordable and provide the services and amenities you need to ensure your comfort, such as a gym, breakfast and WiFi. You can look forward to a little bit more at a 4-star hotel — think upscale furnishings, premium toiletries and extras like spa centres.
