Methodology: The ranking is compiled considering the properties listed on Bed-and-Breakfast.it and is based on the aggregation of reviews published on Bed-and-Breakfast.it, Google and TripAdvisor. The score takes into account both the average rating and the total number of reviews, rewarding properties with a more solid reputation over time. Only properties with a minimum number of reviews are included, so as to ensure the statistical significance of the result. The ranking is updated periodically. - Learn more

The ranking formula

The position in the ranking is calculated using a weighted Bayesian average, a statistical method widely used to make rankings more reliable.

Unlike simple arithmetic average, this system takes into account not only the average score, but also the number of reviews received. In this way, structures with few reviews but very high votes are not automatically favored over those with many reviews and more established ratings.

Reviews from Google and TripAdvisor are included in the calculation through a conversion from a five-point scale to a ten-point scale.

The formula used is:

Score = (n x R + C x M) / (n + C)

Where:

n = total number of reviews received by the structure
R = weighted average of the structure’s reviews (with Google and TripAdvisor reviews converted to ten-point scale)
M = weighted average of all structures on the platform
C = average number of reviews per structure on the platform
