Even though we arrived late, the host waited for us at the train station to walk us to their house. It was very kind and their house is only a short walk from the train station. Their house is one level, which was a relief because we did not have to carry our big baggage up any stairs.
The room was clean and spacious enough. We were very comfortable. Some nights one host stayed in the house which did not bother us at all.
On our last night, we were invited to have dinner with them (Traditional Japanese Onabe!). They were very generous and we throughly enjoyed talking with them. They helped us plan trips by train and gave us recommendations about where to go in and outside of Tokyo.
Overall, this was the most comfortable stay out of the 3 locations we stayed at using AirBnb. There are lots of reasonable restaurants, a grocery store and convenience shops in the area. We did not mind spending extra (on top of the JR Rail Pass) to commute using a private rail in order to get to the Shinjuku JR station. Every night we looked forward to heading back to a quiet and comfortable room. They also let us use their washer and dryer.
The hosts can speak Mandarin, English, and Japanese, which made it easier to communicate and made our stay even better.
We look forward to staying with them again if we visit Tokyo again.
