My friends and I stayed at Yuka's place for a week. The place is very clean and comfortable. The location is okay. There are many small convenient stores around the area for you to get everything you need. Yuka's place is a bit smaller than I expected. I would say 3 people is the max.
One of the biggest disappointment about my stay is that they only offers 1gb portable wifi for you to use daily. Even it's says 1gb, but it'd feels like 10mb. My friends and I used it up within a hour. The house doesn't offers wifi, so the portable wifi egg was all we have. Luckily my friends has free data roaming or else we will be stranded without internet for locating location in Tokyo.
