The property is a gem within Shinjuku. For a price per night that is slightly cheaper than hotels in Shinjuku, David's unit is spacious for two people (and just enough for three people) and accessible to the railway (although not the JR line, only the subway, but that's OK). My husband and I (with average Asian height and weight) could move comfortably around the property.
We also appreciate that David is very responsive to my queries. In fact, I had very limited questions to ask because he gives detailed information about everything that I could possibly inquire. I would definitely recommend this unit for first-time Tokyo travelers or those who intend to book a property just to sleep/rest in between a series of daily Tokyo tours.
