Overall:
Comfortable size for 1-2 travellers. Location is at west side of shinjuku near more of a residential area and would work better if this is not your 1st visit to Tokyo. A bit noisy at night with cars passing by at random hours.
Location :
Accessible by bus to shibuya/shinjuku station directly and close to a subway station
Have to walk slightly uphill to reach apartment
Amenities and responsiveness :
Host was super quick and responsive. Provided decent toiletries and towels for stay
Neighbourhood:
- can be a bit noisy after hours (midnight ) depending on your neighbours with the thin walls but in general ok
- cars will drive past the neighbourhood at odd hours (in the middle of night ) and could get quite noisy
