6 of us stayed for 5 nights during the spring. We appreciated the proximity to subway stations, but as advertised, noise from the trains is noticeable. We didn’t mind the noise too much, but sometimes the train causes the house to vibrate. Since it is a traditional style house, some of the taller people in our group had to be careful passing through doorways. We felt that 6-7 people is the right group size to stay in the house comfortably; any more and someone would need to sleep in the living room. While we never met the hosts, Yuko is kind and very responsive to messages!
