constructively evicted

On January 1, Mrs. Irene Kern leased an apartment from Colonial Court Apartments, Inc., for a one-year term. When the lease was entered into, Mrs. Kern asked for a quiet apartment and Colonial assured her that the assigned apartment was in a quiet, well-insulated building. In fact, however, the apartment above Mrs. Kern’s was occupied by a young couple, the Lindens. From the start of her occupancy, Mrs. Kern complained of their twice-weekly parties and other actions that so disturbed her sleep that she had to go elsewhere for rest. After Mrs. Kern had lodged several complaints, Colonial terminated the Lindens’ lease effective February 28. The termination of the lease was prolonged, however, and Mrs. Kern vacated her apartment, claiming that she was no longer able to endure the continued disturbances. Colonial then brought this action to recover rent owed by Mrs. Kern. Will Colonial prevail? Has Mrs. Kern been constructively evicted? Explain.
