What indicates the quality of a hotel’s service?

Star ratings are a widely recognized indicator of a hotel’s service quality. These ratings provide a standardized assessment of various factors that contribute to the overall guest experience, including service, amenities, cleanliness, and management. A higher star rating typically suggests that the hotel meets more rigorous standards in these areas, which directly correlate with the quality of service guests can expect.

The other options, while they can influence a guest's perception of a hotel, do not directly measure service quality. The number of restaurants available might enhance the dining experience but doesn't reflect the service level itself. Proximity to tourist attractions is relevant for convenience but does not indicate how well the staff will serve guests during their stay. Similarly, the hotel's size could affect the atmosphere and scale of operations, but it doesn’t necessarily equate to better or worse service. Thus, star ratings serve as a more comprehensive gauge of a hotel’s service quality.
