The apartment is very good. Great neighborhood, metro, restaurants, shops... everything is a short walk. Very conveniente to Yamanote and other JT lines (especially if you have a JR Pass). The apartment is super clean, has all the amenities for cooking and a washing machine is great for long travellers. Communication with the host excellent, easy check in and check out. Koichi picked us up and took us to the station, which is nearby, but with bags it can be a little more difficult. Excellet wifi and the portable internet as also a great plus.
