The hotel front desk has a small map with all the nearby transport stations all plotted. It would probably be hard to figure out where the hotel stands if you're just looking at a generic JR map, IMHO. We went in Feb and i think that's "lower" season than now. I think you probably would need to start your bid at at least 115 or 120 and go from there. I think the rack rate was about 240 to 280 when we went, but then our 2nd stretch of days included a local long weekend (nonetheless, our pre-Hokkaido single night stay in the middle of the week was similar in winning bid price to the one that covered the long weekend) If your main interest for this trip is Roppongi, i would also suggest you try a Shibuya hotel, as there are direct shuttles to and from Roppongi Hills and Shibuya train station. Not sure about the PL options there though. But this hotel is close to Yurakucho (and Ginza), and the multi-transfer hub Shimbashi station (one JR away). Lots and lots of cool authentic eats (and a Bic Camera that opens late) around Yurakucho station. You can also take the very-scenic ferries near this hotel to and from the older areas of Asakusa (where the famous temple is, and then Ueno area for traditional products). Definitely different from Ikebukuro. (I too had stayed at Ikebukuro no fewer than 4 times before, and found this a very nice change).
