My stay at Hotel Amanek was reliable and very convenient, as it was close to a train station.
The front desk staff were informative and even gave me a map with pictures when I asked for directions to a bus that would take me to Haneda airport.
I stayed in a single room and it was small, but everything I needed as I wasn't spending time at the hotel other than to sleep. I was able to fit two fairly large suitcases inside the room, but they were able to go behind/beside the front entrance/door without obstructing too much of the small walking area between the door, bathroom, and bed.
There was also a Family Mart around the corner so I was able to grab quick snacks between going out and coming in from a long day, which was very convenient.
