Hotel Onyx

Hotel Onyx was a hotel located in London.

After being contacted by Rani Chandra, (AUDIO: SOS) Cleo Proctor arranged a meeting with her on the hotel. Cleo asked her brother Jordan to go with her. Though he used to walk through that street all the time when he worked on the Tottenham Court Road, Jordan claimed to not remember the hotel existing.

Inside, they were instructed by the receptionist to go to Suite 13 to meet Rani. Upon entering the room, however, they met a holographic projection of her. (AUDIO: Hysteria)

Behind the scenes
Although the hotel's name is given neither in Hysteria or in Lost, it was written on the transcripts provided by the BBC.
