Having a pocket wifi was the highlight of this listing. And the air conditioning worked really well. This would have been a great base for someone doing big day trips out of Tokyo and wanting somewhere to sleep in the evenings. However, this was not right for our trip. Unfortunately the restaurant below the apartment is extremely loud and does not close until midnight, and the doors of nearby neighbours are loud and heavy and make a painful scratching noise when they open. There was lots of light in the room which made it difficult to sleep despite the curtains. It was in an ok area- close by train to Shinjuku but around the area was not much. You would need to walk either back to the train station in Sasazuka to have convenience stores or food or you would need to walk 1km to a lively area in shin-katazawa.
