Super impressed with the final landing page! The design feels both premium and welcoming, and the mobile-first layout makes the content very easy to browse. The sticky “Check Availability on Airbnb” CTA is a great touch, and the sections flow smoothly from trust points to photos and reviews. Overall, the work is fast, clean, and very professional.
