Weekly cleaning is good for you because you will see how he treats your property and avoid potential significant damage . For example I just had guests for 2 nights who turned on the heating on 25C and kept the bathroom door closed all the time so the bathroom was left extremely humid. There was no damage after just 2 days but if they have stayed for a month I would have mold on the bathroom walls for sure.
ps
anyone who rents the place up to 28 days, in most countries is considered as a guest. After that he becomes a tenant and gain tenant rights. This is why most hosts have 28 days max stay. I assume you are familiar with a law in your country and will make him sign a contract to protect yourself and your property
