WorldStayTracker.com allows you to compare average hotel prices in 35 major cities worldwide, with data updated daily.

The averages are calculated from the 60 most popular hotels on Booking.com, the world’s largest hotel booking platform, for each of four combinations: two rating categories (three- and four-star hotels) and two advance booking periods (15 days and two months in advance).

This means that 60 hotel reservations are checked for each of these combinations, resulting in 240 prices registered daily per city. Due to overlap in hotel availability between the 15-day and two-month booking windows, approximately 60 three-star and 60 four-star hotels — 120 hotels in total — are monitored per city.

If a city lists fewer than 60 properties, it means that there are not enough hotels that meet the rating, date, or other criteria (e.g., breakfast included, a minimum review score of 7) or that fewer than 60 hotels have available rooms for the specified check-in date.

When a city has exactly 60 hotels, it indicates that there are likely more than 60 qualifying hotels, with the most popular 60 being selected. Note that popularity is defined by Booking.com and is different from the review score.

Monitoring 120 hotels across 35 cities results in about 4,200 hotels being tracked daily.

By clicking on a city card, you can view a price distribution chart for the hotels included in the average price calculation, along with a list of hotel names, links to their Booking.com pages, review scores, number of reviews, and prices for booking a room with breakfast.

On the Trends page, you can find a line chart showing average prices for each city over time. Filters allow you to select specific cities, ratings, and booking periods for comparison.

The Rating page features a line chart comparing average prices between three- and four-star hotels for a selected city, with filters to adjust the city and booking period.
