New tenants moved into a new renovated apartment. In the contract it stated the apartments were non smoking apartments. The apartment has it's own private terrace . However tenant told me that they had been smoking in the flat due to weather conditions * rain * and now we notice the smell of the cigarettes filling up the communal area=. I know that it is not against the law to smoke in the flat but it is stated in my agreement its a non smoking building. Yet they have decided to go ahead and smoke. What type of letter would i NEED to give them about this.
Any ideas very welcome
