Sweet Poison Rooms in Saarlouis-Fraulautern calls itself an erotic hotel that is a little different: six themed rooms for couples, booked by the hour or overnight with a sparkling-wine breakfast. The rooms include the Exotic Room, the Hypnotic Suite, the Kinky Grotte, the Secret Garden Suite with a bathtub, the Sweet Poison Playroom and the Studio Wetroom, a BDSM room with a St Andrew's cross.

Adult play equipment can be rented to go with a stay, there is a wide choice of drinks from wine and champagne to cocktails, and the house photographer offers erotic photo shoots during a visit. The whole house can also be hired as an event location or a photo and film set. Check-in is possible around the clock by arrangement, and the hotel is open on public holidays.
