The apartment was very clean and comfortable. The room is small but it has everything you need. It was quiet, in a quiet place.
The apartment is far from Tokyo, although there are trains and buses that connect with the places of interest in the city, though, it takes time to get there.
I recommend to look for convenient combinations of transportation cards or something that can help you to save money. In my opinion, transportation is one of the most expensive things in Japan, and we had to spend a lot each day to get to the center of Tokyo.
