I really recommend checking the hotel website before making a bid. The prices can vary drastically by changing dates. I was able to get two nights for just over 33,000yen including all the taxes and fees for 4/30-5/2. As for ways to get to the hotel, I believe the yurikamome (the little automated train/truck thing that runs between odaiba and shinagawa) has a station that is connected to the hotel. At least I remember it being very close. By the way, you can get a lot of "extra bids" for tokyo 5 stars by adding other areas nearby that have no 5star hotels. Chiyoda only has a 1star, Narita only goes up to 3 and Shinjuku only goes up to 4. Be careful with your pricing though because you may end up at a different hotel in Shinagawa I think it was.
