We stayed here at the end of Feb for 4 nights and found the hotel really good. The room was standard in Japan I.e. small. We had two medium suitcases with us and only able to open one of them fully. The hotel was easy to get it and a very short walk from exit 6 of the Akasaka station but please note that this exit only opens till 10pm.
The little touches from the hotel were great, free facial masks and massage gel, as well as a very good selection of tea in the lobby. There were also free bottles of water in the fridge, so we didn't have to buy water at all when we were there. They have most of the things that you need in the bathroom provided, shiseido shampoo, conditioner and body wash, as well as hairbrush, toothbrush, body sponge, q-tips etc, so basically I didn't really to bring most of my bathroom necessities.
The area was good with many convenient stores and a few places to eat around but the area was not crowded at all. The hotel was only 10-15 mins walk from the Roppongi area too.
The wifi Internet was excellent and super quick. We stayed in a number of hotels in Japan and this one was one of the best ones we have stayed in, highly recommended.
