Excellent location few minutes walk from Shibuya station. Plenty of shops and restaurants around the place. The place has two toilets, two showers and very clean. Misaki is very responsive.
Small place !! Approx 70 sqm (2 floors combined). With 9 adults will have little room to move around and definitely not enough space for 9 suitcases.
There are 3 double beds and two single beds so 9th person will have to sleep on floor mattress.
I recommend no more than 6 adults (the price still not bad divide 6).
