Though the hotel's address is in Yoyogi, it is actually less than a five-minute walk from the south exit of Shinjuku Station, and close to Nishi-Shinjuku. Shinjuku Southern Terrace, a shopping and dining complex, is adjacent to the hotel.
Hotel Century Southern Tower is, as the name suggests, located in a skyscraper which towers over the Shinjuku Station area.
Rooms are small and spartan, with the smallest Single room measuring in at 19 square meters. There are empty refrigerators in the rooms, with no minibar products offered.

High-speed wireless Internet access is available, free of charge.
Hotel amenities include a fitness center, a Kinko's business center, and four onsite restaurants. There are also offsite restaurants on the lower floors of the building.
