Clean, apartment on 2nd floor of a small hotel/apartment complex. Located on the edge of the Shinjuku nightlife area, 1 min walk to Nigashi-Shinjuku station and a 15 min walk to JR Shinjuku station. Main issue was the noise. Very thin walls/windows as street noise disrupted my sleep each night (could hear people walking in heels!; talking outside; sirens and the next door renovations started at approx 8am each morning). Tiny bathroom although I realise this is common in Japan. Reception staff helpful and it was great we could leave bags before and after check-out.
