As mentioned, the rooms are TINY, but it's what you get in Tokyo, they are immaculately clean and well stocked with supplies. The rooms are modern and there was free high speed internet. The hotel also had laundry facilities for about 500Yen.

The breakfast buffet is a little bit boring and isn't changed much say to day, but wasn't an issue for us. They served toast, cereal, rice, fries, chicken, soup and stew each day, so little variety.

The location, which is a short walk from Shinjuku station is excellent, I didn't see any of the 'red light' district supposedly around the hotel, the whole area is packed at all hours.

The only minor downside was that the rooms were fairly noisy.

Stayed at this hotel for 12 nights in a single room. A very good size room for Tokyo. Also a reasonable room rate! Was happy to find haning space and a shelf above it for clothes storage. Having stayed at a couple of hotels in tokyo before, this was a luxury li hadnt previously had. Room had a sweet little couch under the window, a quite nice bathroom, one that even had a bath. Once again, relative to other japanese hotels i found it to be 'spacious' you cant judge these hotels by their counterparts in other major cities in the world. Its just not the same here. Only had breakfast once but it was a nice yet not too extensive buffet. If you request not to have your room serviced you are issued a 500 yen voucher. Although cant refuse service 2 days in a row. So I did it every second day and managed to accumulate some money for nothing! Great!
I found the location very convenient to shinjuku area and station. It was central to so many shops and caves I wanted to visit in the area. Some people have commented on the area being a little unsavory. I didn't find it anything to worry about at all. It may be a little off putting if you have a family and are venturing out at night though. I which case the back path mentioned by other posters is ideal. It completely avoids the African pimps. Though they know who not to harass.

Absolutely amazing location, right near the Golden Gai. The free buffet was pretty useless, but maybe that's because we are vegetarian and therefore had not much at all to choose from. Meat eaters might find the buffet better. Still, can't complain with free food. Rooms are tiny but cute, and I was really comfortable. The toilets, as in most of Japan, are awesome.

We stayed here for 4 nights in January, on our first ever trip to Japan. The location is excellent, in the heart of Shinjuku. It provides a great opportunity to explore the local area, especially at night when it comes alive with bars, restaurants and girls shows! The hotel is about 8-10 minutes walk from the train station, allowing access to the subway and trains into the main Tokyo station.
Great value for money, and the room included a buffet breakfast. It wasn't amazing, but it was very good. Wi-fi is available in reception but I couldn't get it to work in the room. The room was small, but clean and modern. I think the room size was typical for Japan, so this is not a criticism. All in all, a great place to stay and I would happily stay here again.
