This is a great location to the Shinjuku station: close enough to walk, far enough for some peace/quiet. The host was quick to respond to our needs (pocket wifi didn't work when we arrived, she provided a replacement quickly!). The unit is definitely small, but was fine for 2 adults and 1 child (I would be a bit nervous for 3 adults - but likely doable if you're not planning to spend much time inside). The futon-bed is actually quiet comfortable (someone else had commented that it wasn't so - I disagree - it was super comfy!!).
