A nice private place with small kitchen that you can cook small meal. A bit struggle at check in as host was not home during early hour of check in period on my check-in date. Though he communicated this about a week in advance. So I had to delay my check-in time and paid extra for baggage deposit at Tokyo st.
If you have large baggage, use station's south exit and then cross the road, you will find an elevator going down to street level. But note that elevator has operating time as it closed during my early hour departure (5am).
Overall, a great valued place in the center of Tokyo.
