Ok firstly, the hotel is fantastic. It is right in the heart of Ginza which to me is like teh Manhattan of Tokyo. You literally have to navigate your way through brand name buildings of Cartiers, Louis Vuitton, chanel etc. The location is fantastic, easy 3-4min walk to 3-4 major subway lines. The hotel even cheekily let us check iin early. We got the night bus in and just walked from Tokyo Station, 8-10min walk. Starbucks, McDonalds, 7-11, am-pm, Family mart, The Tokyo Fish market are all within a 3-10 min walking radius. The hotel itself has a fridge in everyroom, radio, TV free internet, A good proper Bathroom and actual proper Twin rooms. The service was fantastic and polite. EVerything was changed everyday! We paid about 35GBP pppn in a twin room so about 70GBP per night for the room booked through Rakuten.
I would surely recmmmend the Hotel. Its got plenty of CHEAP (cheaper than Osaka) eateries and japanese retaurants close by. I could not find any drawbacks abotu staying here.

strategic location, friendly staffs and easy access to metro.
the room is not spacial but enough for those who only looking for overnight rather than room pleasure.

We stayed in a triple room and although it was cosy, we managed to all squeeze in. The towels and toiletries are changed and replenished daily and are of a high standard.

We ended up staying an extra night because it was such a good place.

Be careful. I arrived to find this hotel was under major renovation. Instead of closing this virtual building site, the hotel remains open with a small note in the elevator stating "noise and vibration will occur from 11 am to 6 pm". Quite unbearable after an 18 hour flight. Shocked to find the construction began at 9 am the next morning! No breakfast room because that too was under renovation, but the relatively cheap price excuses that. The only redeeming thing is that the beds are comfortable, the rooms of fairly good size (for central Tokyo) and the location is in a quiet side street of Ginza. I highly recommend you contact the hotel directly to find out about the state of renovation before booking, unless you don't mind pneumatic drilling over your head.
