For the average traveler, a hotel's star rating is a crucial guide for choosing accommodations. There are multiple ratings, ranging from one to five stars, but what are the criteria for each rating, and how do they differ in terms of service and amenities? This article will provide the definitions and standards of hotel ratings from one to five stars (including domestic and international differences), the specific differences in service, facilities, and hospitality, typical hotel chains for each rating, market prices for accommodation (including domestic and international differences), how to choose a rating based on the intended use, and an analysis from a real estate developer's perspective. This article explains, in an accessible and commercial manner, the impact of hotel ratings on towns and regions.★

There were no particular inconveniences and the trip was very comfortable!
I had no trouble finding directions or places I wanted to go. When I got lost on the subway, a local person kindly helped me out, and I felt the warmth of people there, making it a really great trip.★

I used it in Korea without any issues! Wi-Fi is so ubiquitous in buses, restaurants, cafes, public institutions, and more, I had a ton of data left over. I'll definitely be purchasing it again at a lower price!★
