This is a great place to stay, a wonderful hospitality, a great neighborhood and easy access to many other places around Tokyo.
The communication to the owner is really speedy and we felt very supported with any questions we had.
The room can accommodate for five, however we felt very comfortable for the two of us especially as we had a lot of luggage with us.
For five people it may be great if you knew you didn’t hang out for too long in the room :)
