Convenient location, easy to get to and from. Close by train to shibuya, which makes it easy to get around the city. You can get pretty much anywhere in ~1 hour. As for the room, it was nice, if small. Had plenty of towels and sheets, and enough futons to sleep 3.
Some things to know
-the loft is probably too small to sleep 2 people
-the bed is actually 2 crib mattresses pushed together. It works, but you may want to lay one of the futons on top of it for comfort
-washing machine but no dryer. Hang your clothes in the shower and set the fan to the heater setting
-I payed ~$1400(US) for 25 days. It was a very good deal.
It isn't luxury, but it is clean and gets the job done and the price is right
