We stayed at the Shibuya Granbell Hotel at the end of our Japan trip in Jan this year, and we arrived to the biggest blizzard Tokyo had seen in at least 10 years. So THANK GOD the hotel was close to the station. One of the ladies from the hotel came out and tried to help us drag our bags through the snow, which was lovely because the weather was dreadful!
The rooms were pretty decent. I read that they would be small but I found them to be adequate, we didn't spend a lot of time in the room. The lighting was very dim, which was irritating when trying to get ready. Wifi is available free with a deposit from the front desk and the showers were hot, what more can you want?
The breakfast HOWEVER was so so so so god awful. There is a choice of 2 places (fancy right? WRONG!) We tried both, after the first was mostly inedible we thought it couldnt get any worse. Wrong again. The downstairs one was stone cold, and they didnt even both to try to keep the food warm - the scrambled eggs were in a fruit bowl? You honestly couldn't pay me to eat at those places again.
So, location - fantastic, room - clean, warm, cozy food - dont even waste your time and stomach space
