Satisfull was a good host. He response rather quickly to all our queries and requests. We arrived late afternoon. The Reception office was already closed, however this is not a problem, as the instruction to get the key in the lock box, instruction and info about the appartment is adequately spelled out in the info pack emailed to me earlier.
The appartment is small, however by Tokyo standard it is reasonably sized. The facilities provided are as described. The kichenette is small, just consisting of a hot plate next to the sink. No serious cooking, just reheating of food.
Even though the nearest station was Shim-Mikawashima (about 300 m), it involves a lot of trains transfer to get to downtown Tokyo.
The best station to take was the Nishi-Nippori station (about 800m).
