The room has decent size, compares to hotels in Japan in general, but very clean, and organized. Pre-packed breakfast was good and comfortable,, The owner couple are very nice people, and always ready to help.
The biggest attraction is the location, you are away from the noisy city center, so you can get a peaceful night sleep after an exhausting day traveling, and it’s not to far to get to all the actions, only about 10 minutes walk to Nishi-Kasai Station, where the Tokyo Metro Tozai Line takes you to the city in 10+ minutes.
I also discovered a great & cheap way to get to both airports from the hotel, the direct express bus from Kasai Station, which you can easily walk there in 20 minutes, or 1 stop train rider from Nishi-Kasai.
I definitely recommend it, will go back there next time in Tokyo.
