The room itself is basically fine, when I arrived it was in okayish condition, the house was very dirty and dusty tho and I have to say this made it much harder to enjoy the accommodation. Also, some parts of the house seem to be in bad condition in general.
It was extremely cold (~ 7-9 degrees Celsius inside the room) it is possible to heat the room but the rest of the house still remained very cold.
To the location it might be said, that it is not centrally located IN Shinjuku but rather on the edge of it. I was told it would be in walking distance of about 15-20 mins from the station but even well know Gmap calculates 23mins to get there (from the closest entrance). As the station is rather complex and big it might thereby easily take 25mins, so I think the estimated time is a bit embellished. Ofc, this is only a few minutes extra per day but still might be good to know!
