Many non-residents are using the swimming pool. A group of several people came between 10PM and 4AM, and while drinking alcohol, they made a loud noise and played music at a loud volume, which was extremely insane. People who lived before and moved about half a year ago also come with friends at midnight and make a fuss. There are also groups who come with small children in the evening, probably homeless, and sleep in lounge chairs until dawn. Most of the people who seem to be residents are gone by about 9 PM, but after 10 PM, there are several groups of people who come by car from the outside and make a fuss with bad manners every week. I contact the police when too noisy and can't stand it, but I'm reluctant to contact the police too often. Is it possible to somehow stop the use of annoying people outside?
