The places I had to visit were very scattered so I picked this hotel for its central location. It was just a few minutes from Nishishinjuku Station and about 15 mins from Shinjuku. When I checked in the staff told me I booked a smoking room, which I didn't notice when I made the booking, and unfortunately all non-smoking rooms were unavailable on that day. At my request, the hotel kindly allowed me to change to a non-smoking room on the second day. Thanks a lot for their help.
