Five-star Airbnb ratings depend on reliability and accuracy rather than luxury features, with cleanliness, functional amenities, and fast host communication being the primary drivers of guest satisfaction. Data from over 6,000 Cotswolds reviews shows that guests reward properties matching their descriptions and solving problems quickly, while a single oversight like a dirty oven or broken heating can reduce bookings. Hosts should prioritise hotel-standard hygiene, comfortable bedding, fully equipped kitchens, and honest property photos over expensive extras to achieve consistent five-star reviews.
