Koenji Junjo Hotel is a guesthouse a 3-5 minute walk from Koenji Station in Tokyo, where guests sleep on futons laid on the floor rather than on beds. Private rooms are small, about two to four tatami mats, and toilets and showers are shared but clean. Rooms have air conditioning and Wi-Fi, and three shared toilets are on the same floor. The walls are thin, so voices and movement from the next room carry through.
