Rumika was very easy to communicate with a did her best to make our stay enjoyable. Very helpful.
The house is big by Tokyo standards and although not very modern, it has its own charm. Lots of space for 4 adults and one kid. It's next to a good street so lots of options for food and drinks. One negative is that the closest station isn't JR but we used buses and is only 5 mins to bustling Shinjuku.
