Sei´s description was accurate about everything, and there was a book with information about the area in the house, as well as information usable within the flat. It´s a tiny flat, but suitable for two. Area is calm and quiet, away from the urban city areas, and maybe a little bit to far from the centre city when it comes to public communication, but everything is pretty far in Tokyo... Thought the northwestern parts of the city aren't too far off, as is written in description, and you can be in Shibuya in about 40 minutes from door to door.
Being in Tokyo wintertime is for the cold ones (read me) pretty chilly, also mainly indoors. Sei has a good heating system to use, but the apt is still a bit cold - which, I believe, is maybe normal for most places in Tokyo. It was very clean, and most facilities needed were provided. There is also the possibility to do laundry in the flat, which is always very good in hand. So overall, very good experience. Definitely recommended for two!
