The single was perfect for me, as a solo traveler. It’s small, but very clean, and very comfortable, and having a shower in each room is the best small luxury. Yui & Yui are very kind and helpful and I would not hesitate to recommend them as hosts. The location is great, less than 5 minutes walk from a subway entrance and two stops from Shinjuku. There are tons of great little restaurants & shops within walking distance, too. I loved it, and would happily book again next time I’m heading to Japan.
