"We stayed 4 nights at Groove Hotel in July. The hotel starts on the 18th floor of the Kabukicho Tower building, and we were on the 26th floor. The floor to ceiling windows of our room (not sure if this is all the rooms, but we had a Premier King room, I think) were amazing! The city view was super cool. The bed was big and comfortable, and the shower had amazing water pressure. The breakfast was expensive, but very good. Its a buffet with lots of good choices. This building was also a concert venue among other things. There were several restaurants and arcades right in the building. And, once outside, you were right in the middle of everything: shopping, eating, arcades, entertainment... and a 10 minute walk to Shinjuku train station. I would absolutely stay here again!"
