Hotels tend to be pretty consistently good when it is over a certain price point, and at any higher price point, all you get is better views/location (and may be some amenities such as gym or pool) - aka, quality caps out and just becomes expensive.

Airbnb prices are quite correlated to quality. High priced airbnb (for example, a holiday lodge) can be _very_ good for the price. But airbnb is a sort of buyers beware type deal.
