Naoko’s Airbnb was overall really good. It’s about a 5min walk from Higashi Shinjuku station.
The karaoke bar downstairs was used every night we were in the Airbnb, however you can’t really hear it in the Airbnb, and it is closed by around 11pm.
The windows of the Airbnb were however very thin and it would get very cold if heating is not on. The Airbnb is also facing a road so you can hear a lot of street noise. However, the bedroom area has sliding doors which blocks the noise well, so I had no issues sleeping.
Overall we enjoyed our stay at Naoko’s Airbnb, it was quite spacious for a Tokyo Airbnb.
