How is my 'Average Rating' calculated?

We calculate the rating on based on Stayed date (aka Arrival Date), not reviewed date as follows:

6 months – re-introduction of the 6-month if your hostel has had reviews in the past 6 months 
12 months – if you have not received reviews in the previous 6 months 
18 months – if you have not received reviews in the last 12 months 

You can see your average rating on you Hostelworld page, as well as in your Hostelworld Inbox

Or on-line on Hostelworld.com :

* Sometimes you will find that not all reviews are published on Hostelworld.com, but do appear in Inbox. This is due to the language setting the reviewer selected when leaving review. Select 'All Reviews translated into English' to see all.
