We recommend this place, would have stayed here on our way back to Tokyo if it had been available.
The location is good. The beds/sofa very comfortable. A/c, shower, washing machine etc works well. Full size fridge, microwave and toaster (a rare find in Japan), kettle are included though no cooker. Tea and coffee (instant) are provided.
We were confused by the directions but once we got there, each time after that it was a breeze to the station. It’s well connected to other parts of Shinjuku and Shibuya, which is where we spent all our time.
Access is via a small alley and it may look plain but a very comfortable place made better by the responsiveness of the host/staff. She explained how to use the Ac/hot water/washing machine and brought over the iron/ironing board when we asked.
A number of convenience stores are close by where you can buy breakfast essentials and any other meal (sandwich’s and local prepared food). There is a McDonald and some local restaurants near the station.
