We loved our stay here. We were a group of 5 adults and had plenty of room to live comfortably for the duration of our stay. The bathroom was also spacious and being able to do our own washing was a bonus. The downside to our stay was that there were no windows in the rooms so losing track of time was an issue. However, being in the basement meant that we were able to make a lot of noise without disturbing any of the neighbours. Location was also a bonus as we were only 2 stops from Shinjuku Station and a short walk. I would certainly recommend staying here if you have a large group of people and are looking for value for money.
