This is a great location if you would like to live close to Shinjuku and Shibuya area. It is about 2 minutes walk away from Yoyogi JR train station. And also if you are not planning to stay all day in the house.
Be very careful when you climb up the ladders onto the attic (and please do it without socks). You may slip and fall. You will also most definitely hit your head. We try not to go up unless we really need to.
Ventilation isn't great on first floor as there are no windows.
Bring extra toilet papers if you are staying with heaps of people since the place does fit 9 people and none extra were given during our stay. No slippers were given as well so you might want to wear your socks around (and take them off when you attempt to climb to the attic).
