Excellent directions to locate the house. Excellent communication when my suitcase needed to be delivered as a late arrival from the airline. Everything I needed was in the room.
Located in Okubo, which is a little more residential and right next to "Korea Town." I was caught out one night past train hours, and it was about a 30 minute walk from the Shinjuku Golden Gai.
I had two minor problems...I was slightly too large for the bathroom (at 5'8", my knees brushed the opposite wall when sitting on the toilet), and a pair of earplugs would have been fantastic.
