My friends and I (total of 6 pax) were staying here for a total of 8 nights. First thing when we walked into the space that captured my eyes was how spacious the place is. I especially loved the living space with the tatami mats, it was very comfortable and most of the time we spent our nights hanging out at that area. That area too had space to put your shoes. Heaters are provided so you can plug in if you are feeling cold, there is also a space to hang or dry your clothes =) (though the electricity tripped when we plugged in both the heaters at once)
Moving on to the kitchen, though its a small area (its quite a narrow hallway) but it gets the job done, there is an exhaust fan installed so the house won't stink up when you do some light cooking.
Another cool thing about this place is the bathrooms, the lavatories are separated and there are 2 of them (1 upstairs 1 downstairs), and a bathtub/shower area, which is quite a comfortable size to move around nicely.
Upstairs, is an open area which is separated by thin walls and screens into 2 bedrooms (3 beds and 3 futons). The beds were really unique as the headboard has a charging dock and place to store your belongings. The futon area was nice too, just enough for 3 people and luggage. We especially enjoyed the open are to downstairs from the top, when we look down we can see the dinning table!
Another plus side is the location of the place, its only 5 minutes away from the train station, though travelling from this station was a little confusing at first but you'll get used to it after a few nights. Lawson, 7-11, and Aeon are very nearby, perfect to grab a midnight snack.
A couple of downside, the stairs are really narrow and slippery so careful when going up and down with your luggage. Another thing is that the building is situated next to the main road and the playground, so it can get a little noisy at night and in the evenings (at night the building rumbles a little due to cars passing by, nothing to worry about though^^)
Overall, we have a very comfortable stay and enjoyed the place very very much.
