I was staying in a semi-double room on the 7th floor which only had one double bed instead of two for me and my girlfriend.
Although it was a small room, it was enough for short trips.
The staff were polite but those on duty at night spoke little english.
The heat in the room was not stable, i woke up too hot for two consecutive nights.
JR was our main mode for transport, this hotel is 15 minutes away from the west or the south exit of Shinjuku JR station.

Stayed with my kids in this hotel and from our area we take the train to Disney land, universal studio and Tokyo. The tickets are expensive but i heard you can get a special rate by booking your plane ticket with jal. Shopping is abundant in the area . Restaurants are expensive eve at mcdonalds a few blocks away

We stayed here Feb 2010 so it's a late review. Hotel was older than some hotels in Tokyo, but the place was efficient and clean. Location was great, walking distance to gov building and other areas of interest. Best thing was the buffet breakfast which was exceptional, the food on offer was abundant and very good, western and eastern. It was definetely value for money and I highly recommend it. It's better than the other hotel we stayed on our way back, can't remember the name off the top of my head, and cheaper too.

I chose this because of its proximity to a conference venue (Nat'l Olympic Youth Center in Yoyogi) and for that it was very good (~20 min walk). The hotel itself seemed to be undergoing some sort of work - it was shrouded in scaffolding and there were warning signs in the elevator: "Beware of paint smell." I was thinking, "Oh, great!" but experienced zero discomfort in that regard during my weekend stay. The room was clean, but a little tired-looking. That's why I've rated it a 3 instead of a 4. Semi-double bed was comfortable but I woke up at night because the room was hot and stuffy - I couldn't open the window because of the scaffolding outside. The staff were friendly and helpful - directed me to a good restaurant area and were unfailingly cheerful. All in all, a very average stay.
