Location: House was very convenient and near train station, two stations away from Shinjuku.
Cleanliness: Very clean, enough space to stay organized and separate trash as necessary. (Burnable vs non-burnable)
Amenities: Towels, soap, kitchenware were provided. Washing machine and detergent avaliable inside suite. Pocket-wifi was also included.
Akihiro was very easy to contact and very quick to respond!
Additional notes: Some Japanese was needed to operate washing machine, but nothing Google Translate couldn't handle.
Would definitely would stay again.
