The tourists actually found many live maggots in the hotel bathroom. How to protect your legitimate rights and interests in this case?

I believe that many friends will go out to play with their family and friends during the holiday on 10/day. If they go out to play, we will go into the hotel, but the hygiene of the hotel has always been our discussion. Recently, many hotels have been exposed to the problem of substandard hygiene, and if our legitimate rights and interests are violated at this time, how should we maintain it? Let's talk about hotels that have been found to be unqualified. One of them is Home Inn. Home Inn was reported to have seen live maggots crawling out of the sewer in the bathroom. When the people who checked in wanted to take photos and leave evidence, the hotel staff chose to wash them off immediately. So how should we protect our legitimate rights and interests? This friend chose to leave evidence and report the unsanitary phenomenon at home. This friend chose to leave evidence and expose the unsanitary phenomenon of being at home on the Internet. At this point, Home Inns chose to respond. Their only way to deal with it is to avoid the room charge for the third night, because the room charge for the first two nights has already been generated, giving the customer another room. Although the exposure is at night, you can let the hotel take the initiative to compensate you. Like some other hotels, online reporting does not choose to compensate you, but you can choose to go directly to the relevant departments to complain about this hotel. Or if the staff can't handle it, go directly to the hotel owner and ask him to give you an explanation. Therefore, when their legitimate rights and interests are infringed, there are many ways to safeguard their legitimate rights and interests.
