Kentaro's place was easy to get to, a few mins walk from a station which was well connected. A great place to stay instead of paying for a hotel/hostel in the similar price range. The neighbourhood is very quiet and people are respectful, this is not a place to party. Was only a 30 min taxi from Haneda airport.
The place has tons of beds, so great for a bigger group. If your main objective is to spend time exploring the city, then this place is ideal. It doesn't really have a communal area like a living room (unless you sacrifice one of the bedrooms), so bear this in mind.
Each bedroom has AC/Heating. Each floor has its own toilet and seperate shower room. Each floor also has a sink and electric hob. I would'nt quite call this a home away from home, its more of a house with lots of beds for a bigger group; again perfect if your main objective is to explore the city.
