This is a great stay in Tokyo and fit our family of 5 perfectly with 2 in the bedroom, one on the sofa bed and two on the floor. Our host was super friendly and easy to communicate with. She also provided some suggestions for taxi companies to reach out to since we needed to get to Toyosu Market for the tuna auction early in the morning. A few things to note are that for those sleeping on the ground to have that expectation. Location wise, while convenient to Shinjuku and the west end of town, it will take a little longer to get to say Asakusa or Akhirabara. Also, you may or may not need to change at Tochomae on the Oedo line so there's always that added step but that's not to say it's hard to do but just something to keep in mind.
