We ended up paying about $180/night via expedia.com, which was quite reasonable considering the rates quoted on the hotel's website.
We took the subway's Marunuochi line to Akasaka station. There's a map at the station with yellow exits that leads you to points in the surrounding area. It’s a 5-minute walk to the tower side of the New Otani. The hotel consists of two parts, the Main and the Tower. I’m not sure if there’s any real distinction, perhaps tourists in Tower and business travelers in Main?
If you enter via the Tower, the lobby is on the third floor. The first few floors are occupied by office workers, and there’s also an office block extension. We checked in at the Tower and were disappointed to not be informed, until we were in the room, that although we had reserved a nonsmoking double room, we’d been assigned smoking (brick hard) twin beds room. The hotel was fully booked and we couldn’t be bothered to unpack and repack in case a nonsmoking room became available. So that resulted in me waking up with runny eyes and stuffed nose due to agitated allergies.
The room was quite spacious, with a roomy bathroom with the usual amenities: TV (CNN and BBC being the only English channels); Internet access at a ¥1,200 per day (modem cabling is supplied); free tea and coffee; lots of snacks and other expensive goodies in the fridge and drawers; and bedside lighting controls with a radio. The bathroom was well stocked with everything from toothbrush and paste to little bottles of shampoo, etc. The towels were all quite soft and didn’t smell bleached – usually you get one rough and one soft one. The bath/shower functioned well with enough water pressure and a fancy showerhead. There was also a patch of the mirror that didn’t fog after a steamy shower. The toilet was standard, with lots of little buttons to play with!
The third floor connects the Tower and Main with the breakfast area, some touristy shops, and a travel agency. If you’re going to be picked up by a tour bus, make sure you wait in the lobby of the Main. From the breakfast area, one can see the hotel’s famed garden, which is quite large, and the pool and a restaurant are hidden there, too. There’s a pond with koi (do not feed) and mini bridges. It’s quite a peaceful environment that’s perfect for wedding photos. We were lucky enough to catch glimpses of a couple exchanging vows in the hotel – it’s quite common for larger hotels to have Shinto Shrines to wed people.
I was not entirely impressed with the hotel as a whole in that breakfast wasn’t included – it was more expensive that some of the dinners we had in Tokyo. We opted for the coffee shops down the road near the Belle Vie subway entrance. There was also an extra charge to use the gym and hotel pool facilities! It was a nice enough hotel, but not quite a value for the money.
