Grapehouse is a perfect retreat for exploring Koenji and the surrounding neighborhoods. I stayed four nights, and really enjoyed my time there. Would recommend checking out the nearby sentos (public bath houses), of which Sanae has drawn a map with four closeby. The bed was comfy and private. The shared room was a little loud, but that was only due to a group of guests who had little consideration for the other guests. They likely won't be there when you stay! Other than that it's a perfect spot, great value, overall recommend and hope to be back when solo again in Tokyo.
