Highland Park: furnished short-term housing for April-May?

Hi neighbors, My mother-in-law would like to come help us with our baby from mid-April to mid-May, dates flexible, but we don't have enough room to host her. Is anyone renting out a furnished apartment, studio or one-bedroom ideal, for that period? We're especially interested in options that don't have many stairs and allow small children, so that she could watch him (safely contained!) over there. Thanks much, Helenmary Sheridan
