I think it would be unwise for your landlord to allow this. They have little to gain but a lot to lose.
My wife and I rent two vacation homes on AirBnb and other websites. We started with a one night minimum in the off-season and then quickly change to 3 nights. This essentially means we book fewer off-season weekend rentals.
Here's why we did that: It takes 1 night to trash a house. So do you want someone to pay you $200 to trash your house or $600 to trash your house?
You're also playing Russian roulette where every new guest is a trigger pull. The fewer trigger pulls, the less likely you are to take a bullet.
We'd rather a higher vacancy rate with an overall fewer number of guests. In the end this means we might reduce our revenue by 10% to have 50% fewer guests.
Your landlord would have to decide that couple extra thousand dollars a year would be worth hosting 20 random visitors. If that's how the numbers break down the risk isn't worth the reward IMO.
