I have lived in this apartment for approximatively 7 weeks and it was a great experience. This apartment is perfect for travelers with big suitcases since there is an elevator and also place to store the suitcases.
The apartment is small but enough for one or two people.
Some dishes were not perfectly clean, but apart from that, everything in the apartment was clean.
I really enjoy the documentation Zaito provides in the apartment, which explains in English how the appliances works, which is very great for people who doesn't speak Japanese.
The localisation is very great to discover Tokyo, all the main touristic places are easy to access by train. There are a lot of shops, supermarkets and convenient stores around the apartment.
The downside of this place is that it's situated near a big road, so it can be really noisy, even during the night.
Zaito is really responsive, he answered really quickly and nicely to all my questions during my stay.
I recommend !
