Sam was very nice and helped us a lot. He even helped us to book a restaurant before our stay! And he also let us check our luggage prior to our check in time that day.
The house is a 10 min walk from the nearest station, in a very nice and quiet neighborhood. Sam stays in the building too, so he would be in reach most of the time of the stay.
The room was well equipped, a very ideal place to stay for long term stays. I would definitely like to stay at Sam's place again next time I visit Tokyo!!
