We stayed with Kazuhiro for 7 nights and it was very pleasant! We arrived late at night on a weekday (almost 1am), and we felt terrible for keeping Kazuhiro up, but he was thrilled to welcome us. Like many other reviews have mentioned, he put a sign out front and it was very helpful. His place is very, very clean. The space we were given was adequate in size, and felt like our own space within his place. You might get a visit every now and then from his cat Fro, but she's usually only interested in chilling by the sink. She was very well behaved. Kazuhiro was very considerate in giving us our privacy, but he was always down to hang out with us if we wanted to. The shower and bathroom were both very accommodating. We really appreciated the care that Kazuhiro took in making sure we were comfortable and communicating with us.
