I stayed here after arriving in Japan and the check-in process was easy, though I speak decent Japanese they do have resources in English to read and can communicate if need be. The proximity to Shibuya Station and nearby places is amazing and it's very easy to find (~3 minute walk). Despite this I never found noise to be an issue and though there are occasional sirens I don't recall it preventing me from sleeping and the curtains are great for keeping light out.
If you are at all interested in the breakfast buffet, I'd definitely opt to get it included in your nightly fare on Hotels because it would make it significantly cheaper (normally ~¥1900 per adult per breakfast, 990 for kids) and I would do that next time. Great value for what I paid on here for a room with a double bed (~$63 a night) and I loved having a projector in my room to watch youtube/netflix but they also had amazon prime available to log into, as well as other free channels.
The toiletries were pretty good, the hair products were a little iffy for my wavy hair texture but they work.
The staff are polite and courteous, and don't automatically clean your room unless you put up a sign for them to do so which I appreciate.
Overall good experience.
