Ryota's place is a good base to be in and out of. The main metro line is super close and makes it easy to get anywhere, although the surrounding area is pretty quiet and not too much happening. We were 5 people in the space, and found it to be a little small. Main issue was the futon bed, which is barely a futon. It's basically just a duvet on top of a tatami mat - so hard that we woke up with bruises on our hips.... much better for four people and to use just use the two beds.
