Opposite subway station, very easy to find. If location is your priority, then this is a great option in the heart of Shinjuku. Walking distance to the izakayas of Gai alleyway and Omeido Yokocho.
The place itself feels a bit like student accommodation, lacking a bit of homely comforts in terms of furnishings. We could only find one tiny bin for the whole place. The mattress was too soft for our personal liking. There was a washing machine but nowhere to hang your clothes. Some coat hooks at the entrance would be good! If you want somewhere basic but in a perfect location, then this is a good option. For us, it felt a bit over-priced for what you get.
For some reason we thought there was a lift from the pictures, so don't make the same mistake as us!
