Mitsuko's guest house was perfect for our needs - excellent location, spacious living room, clean, comfortable, and the toilet room was separate from the sink and shower rooms so that was a nice bonus vs having them all in the same bathroom. It's on a quaint, one-way street lined with bakeries, markets, bars, and even some proper massage and stretch places. Mitsuko and her husband were very kind and hospitable, making our first trip to Japan so comfortable, memorable and enjoyable. Mitsuko also went above and beyond in offering to drive us to Shinjuku Station on the day of our check out since it was raining heavily and we had awkwardly large and heavy baggage. There were three of us (friends) staying together and we would highly recommend booking this guest house.
