We stayed at Sei's for 5 days. Location was pretty nice; walking from train station to the apt was much faster than I expected since there were tons of things to see along to way. Food, grocery and everything else. The room was a perfect fit for 4 people. I couldn't imagine any better layout. Enough space for everyone. Bed was surprisingly good too.

Although I did not meet the host, Sei, she promptly responded to anything you asked via messages. She also gave more than enough information to make the trip comfortable.

The only drawback was the portable wifi; it's basically useless. Go get your own SIM for much better experience.
