My mother in law and I had a lovely 10 day stay at Risa's place while visiting my college student kid who is JYA in Tokyo. Risa stayed up to meet me when I arrived in the evening and gave us keys to the house and room.
We stayed in a room with two twin beds and a tiny fridge, and a shared bathroom next door.
We did laundry once in the shared machine downstairs and had access to the kitchen, although we really only used the microwave a couple of times.
We took the Keio train into Tokyo every day, shopped at the stores near the Kokuryo Station, did lots of touristy things.
Risa and her father and her dogs were all friendly and welcoming. Risa was helpful in answering questions both by email and in person in English for us :)
We never had Risa cook for us and we were out every day and never were bothered by anything from the cafe downstairs.
Definitely a great stay for us :)
