There is not much difference between the two. Though 5 stars hotels services and facilities have wide range.. They are counted as luxury hotels and their pricing is done accordingly.
The difference is in its number i guess ahaha lol.
Independant Hotel Inspectors have rated the hotel 5 Stars for, Comfort, Cleanliness, facilities and luxury.
5 Star Hotels are more popular as one star hotels are just those undeveloped ones. A 5 Star hotel would be Best Western for example.
