I rent an apartment to a 68-year-old tenant. I wish to take it back to live in because it has an elevator, which is useful for me at 70. I have been told that my tenant is protected and that I cannot give notice. Is this true?

No. You may reclaim your property because the statutory protection granted to the tenant under Article 15 of the Law of 6 July 1989 does not apply if the landlord is over sixty-five years of age or if his annual income is below the applicable resource ceiling for the allocation of regulated rental housing.
