Maki-san is a very welcoming and friendly host. He really got out of his way, meeting me for lunch and offering a lot of wonderful advices and tips. The appartment 603 in which I stayed was very bright with nice windows opening on an unblocked view (this is a luxury in Tokyo where often places can be dark). Having the morning sun warm up the place is great in winter. The flat has a very good size for staying alone or 2 people. Full size kitchen, full size fridge and a washing machine which are great for longer stay. Unfortunately and out of the control of Maki-san, the building maintenance is not great and can come across as dirty and grim.
But it is a safe and quiet place, a few minutes walk from the JR station and lots of shops and restaurants. Idéal if you want to experience how most Japanese people life is like.
