The place is great! Everything looks new and host is super-responsive. Just be aware that you will need to lug your luggage up to the second floor and the stairway is a little narrow (may be hard for older folks).
Location is close to the city but note that you need to transfer between subway lines (which can be a little confusing if you never used the Tokyo mass transit before (like us)).
All in all, a clean new place with a super host!
