It says 4 min from shinjuku but we spent 10+ min to get there from the closest station Nakano-sakaue stn. There was literally nothing nearby.
The place was fairly clean. Stains and dust at the windows, curtains and drapers. The bed and pillows were terrible to sleep in. We got stiff necks waking up everyday. The air quality was fair too.
The outdoor area was useless because its right next to the collective gabage area of the building. Trash would get blown into the outdoor area overnight especially around the Christmas period. We basically woke up everyday seeing trash outside.
We did not enjoy a single thing about this place during our stay, not worth the money either even though its not expensive.
