I've stayed here a couple of times because I like the views from the high floors overlooking Kabukicho. There is another, newer hotel that is close and actually inside the Kabukicho neighborhood that I may check out next time but if you are a first timer or Tokyo, or just want to plant yourself in the middle of one of the coolest neighborhoods on the planet, you can't really beat this place (5 min walk from shinjuku station and accessible above ground of below if it's cold or raining). It's really a 3.5 star hotel and the service seemed a little weary from dealing with Asian tourist groups all day long, but people were friendly and the price is good for Tokyo. Don't expect much from the concierge - better to do your own research and make your own calls on local dining, etc but you should do that anyhow in Tokyo where price and quality are totally unrelated (you can get amazing food for great prices and expensive often means stupid expensive for people who just like to spend money).
If this is your price range this place can't be beat. It's not a great hotel but it's a decent place in an amazing location.More
