Can I sue for disturbing people by playing billiards and poker upstairs?

As long as there is enough evidence, of course, but it is recommended to reflect it to the property department for mediation first. If the adjustment is ineffective, you can call the police and let the police handle it. There is no need to appeal. It should be solved at the police station level. Appeals cost money, and it's really not worth it for such a trivial matter.
