And It Will be registered for a long time. I would like to give the idea about the dislike comment, so wrong photos or comments could be revised by the local Guide users, and help business to grow and give a second chance to that place.
Thanks for sharing your feedback and your idea with us. I agree that the written reviews about places on Google Maps will stay for a long time and for me it’s also good to be honest and detailed.
Please be aware that I’m going to move your post to Local Stories section where usually the Local Guides are sharing their local experience. In case you have any questions, you are welcome to share them on How-tos board and please share your ideas for improvements in the Idea Exchange board.
Please bear in mind that I’m going to remove the Spanish language tag from your post as it is in English. Only posts written in a specific language should have the corresponding label. You can find more information in this article How do I find posts in my preferred language?.
