A listing for a tiny St. Louis apartment has gone viral because of its unique layout in which the kitchen and bathroom are the same place.

The 200-square-foot two-room apartment in St. Louis’ popular Central West End gained notoriety after an ad with a photo was posted showing a kitchen sink and a bathtub separated only by a toilet.

Harold Karabell of S.F. Shannon Real Estate Management said that the quaint apartment was rented out for $525-per-month and the new tenant loves it.

The design had many people wondering if it was actually legal.
