The most popular and effective way to write a review specifically for the hotel property you stayed at is to publish it on the property's Google Reviews or Trustpilot.
Leaving a public review on these platforms is the best way to provide direct feedback to the property management regarding your accommodation stay, and it heavily assists other global travelers when making their own booking decisions.
Please Note: When submitting your feedback on these platforms, please ensure your review specifically details your experience with the hotel property itself (such as the rooms, amenities, staff, and location) to ensure your feedback reaches the right venue!
