We have stayed in Shinjuku and across Japan numerous times. This is the worst hotel by far. The bathroom smelt like sewerage for the entire stay, the room layout did not maximize the minimum amount of space, there was hardly room for our luggage, staff are not very helpful, they do not offer any assistance with shuttles, the rooms were not clean and the bedding appeared old, worn and dirty. The good parts are the location (although next time I’d pay more the Kieo Plaza) and the fresh towels provided by house keeping each day (even when the do not disturb sign was on). By far the WORST part was the rooms on level 7 appeared to be rented “by the hour”. Women were constantly coming and going at all hours of the day, dropping and picking up keys. We know this as we couldn’t get a good nights sleep due to the terrible mattresses and pillows.
