Ko’s place is one of the biggest apartment we have stayed in Japan.. The location is excelllent, it is 5 minutes from Shinjuku station and there are plenty of restaurants and convenience stores nearby. Ko is easy to communicate with and check in instructions are pretty easy to follow. The only problem we had was the wi-fi connection, there was none in the bedroom and even in the other room it wasn’t that good. We’ll definitely stay here again next time we’re in Tokyo
