This was our first time staying at an Airbnb host, and it was a great experience. When we first arrived, Mitsuko allowed us to check in earlier and when we met her she was so welcoming and she explained the stuffs inside the apartment, which was helpful. Mitsuko was also helpful and responsed very quickly whenever we asked something. The apartment was clean and small, however it was spacious for two large baggages, so it wasn't a problem. The only drawback was the toilet, which was too small, and the room can be quite a bit cold sometimes. However, the drawbacks can be ignored as the place is located near Shinjuku and Shibuya, the place is easy to access to and there are so many restaurants and local shops.
Overall, we enjoyed our stay at Mitsuko's and would definitely be our choice when we come back to Tokyo.
