Guest House's space was really nice and perfect for traveling by yourself! The highlight of staying here was that it was literally across the street from Tsukiji Fish Market so you don't have to wake up nearly as early to go line up for the Tuna Auction. Bed was extremely comfortable and while the room is very small, you will feel really comfortable. There was an electronic cooker and laundry machine but I didn't use either of them. The top of the bed also had an outlet that they put a charging station on which had two USB ports and a regular outlet.
Highly recommend and would come back to this place next time I come to Tokyo!
