An absolutely amazing host with good English and great communication. Responses are prompt and went above and beyond to help with an unfortunate situation of ours. She provided clear directions to the Airbnb from each Tokyo airport that were easy to follow. Even with the instructions, she waited for us at Hatagaya train station and walked us to the Airbnb despite it raining.
The Airbnb is a short walk from the subway and only 2 stops away from Shinjuku station. It is also a 20-25 minute walk to Shinjuku/Shibuya areas if you like to explore. It can comfortably fit up to 2 people with anything you would need for the stay. Bathroom is small, but that is normal for Japanese apartments. The bed and Airbnb were very cozy and comfortable to return to each day. Highly recommended just to have Mitsuko-san as a host, the great Airbnb is the cherry on top.
