We enjoyed our stay at Kaen’s place. She left helpful diagrams for us to use the apartment amenities and a homemade map to enjoy the surrounding area which was a really thoughtful touch. There was some construction noise from across the street and noise from the neighbouring apartments but I think that’s typical of a big city, particularly Tokyo. Good food options in nearby Shinjuku. We recommend the Oslo batting centre, about 15 mins walk, to hit some pitches if you’re a baseball fan!
