Midori's place was well-furnished, very clean, brand new and can comfortably accommodate my family of 5 adults. We were not able to make full use of all the amenities since we only stayed for one night (checked in at 5pm and checked out at 7am the next day), but we did not find anything lacking.
The area was quiet and did not have a lot dining options when we stayed over. The nearest public transportation was Shinjuku Station which was quite a walk away, around 10-15 mins depending on how much you are used to walking.
Midori was kind enough to provide a video which walks you through how to get to the apartment from Shinjuku Station. You are also provided with mobile wifi, which is very helpful for exploring the city.
All in all, it was a great stay, albeit a short one. Would recommend for tourists planning on staying in Tokyo for a few days, but the price was quite high for just an overnight stay.
