I booked the single room for 1 night. I think I booked smoking room by mistake, then I ask reception whether I change to non-smoking room. The man and woman at the reception are so nice, they change the room type for me.
The room is clean, wider than I expected, have space for large luggage. The hotel is really near to the train station (shin-okubo, okubo), but there’s no escalator and elevator at shin-okubo station. If you have large luggage, you have to use okubo (north exit) instead.
