Booking.com review

Booking.com is the strongest place to pay for a stay. Its about page reports more than 28 million accommodation listings, including over 6.6 million homes and apartments, in 43 languages with 24/7 support, and the site also sells flights, car rental, attractions and airport taxis. The free Genius program is the main value lever: a free account gives 10% off select stays and rental cars, 5 bookings in 2 years reaches Level 2 with up to 15% off plus free breakfasts and upgrades at select properties, and 15 bookings reaches Level 3 with up to 20% off and priority support. Booking.com says members are never demoted, so the levels stay. The caveats are clear on the Genius page itself: discounts cover 850,000 participating properties rather than all of them, and they apply to the price before taxes and fees. Flights are available but feel secondary. For hotel-heavy travelers, few sites reward repeat bookings this simply.
