Two wheeler parking issue with upstair neighbour

Hello, Last month, we moved to a two story builing, where I live in the ground floor with my family and, there is another family alredy living in upstair. We both are not owners of the property. I have one bike and they have two. As we do not have separate parking place, we park the bikes in our veranda at night. I hired a maid to clean the verenda every morning. Hence, I asked them take out their bikes by 7 am. Here the problem comes, they take one bike everyday but they do not the other. If we call us to take the other bike, then only they take away the bike, if I don't they keep it for whole day/s until they need it. We politely tell them, but they never move their bike. I talked to my land lord. But the problem is not solved. To counter this problem, I also said them that they can keep their bike as long as they share money for verenda cleaning. They plainly denied to share money. So, please advise me how to deal with them in this regard. I have few questions regarding this, a. are they entitled to park their two-wheelers as long as they want? b. are they not responsible for veranda cleaning? So, please advise me how to deal with them in this regard. I thank you for your time Sincerely Siva
