I loved Sean's house during my stay. I used the room of the 3rd floor and the roof window was great when it was raining. The house was super clean and the two toilets were convenient for my 4 member-group. Sean was very supportive and always gave answers quickly when I asked something before/during the stay. The location was perfect for walking from the subway station and enjoying the evening around the station. In my personal opinion, the room of the 1st floor was smaller than I expected. My 4 member-group wanted to sleep separately, so one of my friends slept on the living room of the 2nd floor, but it's depending on each cases. It was just my case. If I strongly recommend Sean's house in terms of location, cleanliness and sleep-privacy among friends. I want to visit again when I go to Tokyo! =)
