The host got in contact with me the week before I arrived. They had a very useful guide on how to get to the house with pictures included. I appreciated how well laid out everything was.
The house was clean and tidy, but it is a small space. That's to be expected in Tokyo though! There was a handy guide on how to use all the appliances, etc because everything is in Japanese. The main problem was the lack of comfortable sitting. You can either sit at the dining room table or the extremely small couch under the stairs.
Other than that, it was in a perfect location close to 2 main train lines. There are a few grocery stores and mini-marts close as well. The neighborhood was residential, quiet, and clean. It was a good break from the lights and noise.
