The San Francisco boarding house where Picard and his officers lodge in 1893, fending off their landlady's demands for rent by claiming to be a troupe of actors.
Mrs. Carmichael's boarding house is the base used by Picard, Riker, Troi, Crusher and La Forge in the Next Generation episode Time's Arrow, Part II, after they follow the Devidians back to nineteenth-century San Francisco.
With no period money, the officers fall behind on the rent, and the formidable Irish landlady, Mrs. Carmichael, repeatedly corners Picard for payment. He explains that they are a theatrical company rehearsing A Midsummer Night's Dream, stages a hasty read-through to prove it, and charms her by offering her a part in the production.
The rooms serve as the place where the team pieces together the pattern of cholera deaths and plans its visit to the infirmary. Before returning to his own century, Picard asks Samuel Clemens to settle the outstanding bill on his behalf.
