Very spacious and very clean... Host can speak English quite well and has outstanding hospitality (he even allowed us to leave our luggage at his place while we tour around Tokyo until the time to leave for the airport, after knowing that our flight was near midnight)...
Location is easy to find but be careful when searching using google map as I was pointed to the street behind (most probably due to gps issue)... there is a 7-11 store nearby and near the Tokyo Metro’s Minowa Station there are some eateries, a Family Mary convenient store and a gym...
