Pretty good hotel for solo travelers around the Makuhari area. It's close to the Shin-Makuhari train station, as well as a couple of shops and a supermarket. So if you want to get something to eat from a convenience store, or take a train out to Tokyo, then you can do that easily.
As for the room, the one I had was a single room. It is small, so you probably don't have enough room to move around in. But it was manageable. For the price, it's not too expensive.
