This is the noisiest hotel I have ever stayed in. The walls and ceilings are paper thin, so you will know when your neighbour is using the shower or the TV, or has the air conditioning on. If you do finally get to sleep, you will be woken early each morning by people leaving, presumably to catch their flights. And if you're trying to rest during the day, you have the nearby sports field and fire station to contend with.
This is undoubtedly a cheap hotel, especially while the yen is weak; whether or not it's good value depends on how much you like a good night's sleep.
Oh, and the WiFi is really slow.
