Location is a 7 minute walk from Nakano-Shimbashi station. (We took the recommended route by GMaps which is an 11 minute walk from Nakano-Sakaue station initially when we were getting to the place with our luggages. If you are considering to stay here do keep this in mind as it might not be very intuitive navigating the train stations and suggested routes especially with GMaps) Overall, location is peaceful and away from the city and is convenient to get to the Shinjuku district.
Check-in details were provided through a linked PDF, which could take quite a while to load without a good connection as it is a rather big file with the details to get in through the entrance at the end. Took a while to get settled in, but overall amenities were as listed and the place was clean.
Space is rather small if you have many luggages, but it is of average Tokyo accommodations. It’s a place to consider if you are looking to explore the Shinjuku area.
