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.

I had a little trouble connecting when I was there. It would occasionally freeze when I was checking directions on Naver, but overall it was fine. It wasn't enough to warrant calling customer support, so I'm giving it a rating of 4. The best thing about it is the low price. Thank you.

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

I like how easy it is to download and that it's a genuine product. I previously purchased a cheap eSIM but it didn't work, so I had to buy a genuine one at the airport. This is the one I'll use when I'm in Korea. I can use it immediately when I arrive in Korea, and there are no problems with the signal. I'll use it again.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!
