How this ranking works
Each hotel gets one number, the Hotel score: its guest rating out of 10, weighted by how many guests rated it. A 9.7 from 566 reviews ranks above a 9.7 from 64. Only hotels rated 8.5 or more from at least 20 reviews are listed. No hotel pays to be listed, and our commission never changes the order. Full method.
