The apartment was a 10 minute walk from various subway/train stations in Shinjuku and the area was extremely convenient, but not very noisy. Midori provided responsive communication, even though there was a bit of confusion on the location on a couple of apartment-related items at first. The apartment had nice furnishings, the shower was nice, and safe.
A few items that warranted a 4-star review:
1) The toilet was visibly not clean.
2) The toilet room had a smoke smell that persisted (Midori offered to have the cleaning crew service the apartment the next day but by then, my friend and I were already set up and jet lagged).
3) There was no extra toilet paper (just one roll).
4) There was minimal laundry detergent. This is minor as I'm not sure if it's a basic necessity that should be included.
5) There was no where to hang dry clothes after washing. A clothes line and clothes pins (or drying rack) would be useful since there is no deck.
6) There were no sheets for the pullout sofa bed. There may have been some confusion whether we needed the sofa bed (two guests) but we were able to request and grab sheets from an external supply closet.
