This is a great place to stay when you visit Tokyo. It's very easy to reach from and to airport. With only 1 stair separating the apartment and the plane.
There is one Tokyo Metro entrance at less than 1mn from the hotel, and the size is really huge for apartment in Tokyo. Overall it's a great value if you like spacious places.
But for those very particular with bathrooms especially, this place is quite dated and could be renovated. It's not really consider as 'cosy' but will definitely suit bigger group/family who need lots of beds.
