Rights as Tenant
I face a big problem the last months and I would kindly ask your advice. My apartment is in an old, typical Belgian building on the second floor. The location is in Ixelles. The floor is wooden and the plasterboard ceiling very thin. Apart from the noise of the tenant upstairs, I have a serious issue with the smells of the tenant downstairs. To be honest, my problem is not with tenant but with construction. Apparently, whatever the tenant cooks in his apartment goes into mine through his ceiling and my wooden floor. He's also a smoker so, every time he smokes or lights incense sticks all the smoke comes into my apartment. In reaction, I have to open the widows all the time as the smoke is really toxic, I got sick from the cold with deep throat pain from the smoke and sometimes because of the really intense cooking smells as the tenant is from Africa. I am starting to have serious problems and although I talked to my landlord, he keeps on telling me that he cant't do anything. I am wondering what kind of rights I have in this circumstance. Could I break my contract and leave the apartment immediately as it is harmful for my health?
Thank you in advance.
