The staff are great. The area is good. The traffic lights have a pedestrian crossing that beeps all day and night. This is easily the only thing I hate abut this hotel. I now have perfect pitch with that intersection sound. I will never forget it. It is a major 3rd note followed by a root note, in case you muso people care. The noise is every minute. Forever.
I changed room and could not hear it very easily at all. That was a vast improvement.
If you are facing the intersection, you may go crazy. If you are facing the internal atrium/chasm/void of the hotel, you may be OK. The staff are great people, by the way. Very friendly. Oh, the breakfast is sort of OK for a Western guy like me. I just want to get as many nutrients as possible before going out all day. Luckily, there is a pretty good Miso soup at the hotel's breakfast dining area (probably every day) that contains seaweed. It is recommended to drink/eat as much of that as you can. If you hate seaweed, then try to change yourself. Just eat it. Apart from that, there were rice things (Onigiri maybe), plus some other basic foods. The cafeteria ladies were very friendly, as you would expect.
