Although I'm Japanese, I think this Airbnb probably works well for foreign visitors too. It's centrally located, quiet and clean. It also has a nice small balcony.
From Narita airport, you can now get to Shinagawa station directly without changing since the Narita Airport Express has resumed service that was suspended during Covid. Although the Airbnb is close to the station, since it's uphill, if you have a lot of luggage, I recommend taking a taxi, which is what I did. I arrived when it became dark outside, so I had a bit of difficulty scanning my passport because it kept catching the light reflection, but otherwise, the check-in process was quick and simple.
Having both the washer/dryer (plus detergent) in the room really helped. The dryer's cycle takes quite long time, so I let it run and went outside. Also, the buttons are marked only in Japanese. The room is quite humid, so the bath towels and washed clothes stayed moist when I just hang them in the room.
I enjoyed my stay.
