Hilton hotels are usually to a high standard, though for the money we paid the room I thought was a little small. Great view however.
All services were done to a high Japanese standard and all meals we had there were of a high standard.

great value for a hotel in Shinjuku which is a fantastic place to stay in and hotel provides a good the shuttle bus service to the station. Walking is easy to the station too - less than 10 mins. And if you are too tired/have too much stuff from the shopping in Shinjuku, taxi is about 700/800 so it's affordable.

we stayed there with our kids who thoroughly enjoyed their time - cute balloons at the reception, thoughtful service at breakfast (one of the service staff cut up my daughter's food into smaller pieces), and the indoor pool and onsen/toiletries - looked forward to taking a public bath!

we got upgraded from 19th to 24th floor (standard to deluxe) which was really appreciated as the furnishings were updated (modern/clean contemporary style that's reflected in the website photos), and the room was spacious. I think I would have been a bit miserable if I stayed on the 19th floor as even the lift lobby seemed of an older style (peach tones/80's decor).

other tips: go to the tokyo metropolitan govt building nearby for a free panoramic view of the city or just right across is the sumitomo building where the top floors have restuarants - try 52nd floor senya restaurant for teppanyaki (great views, food and service).

I stay at this hotel a few years ago on my first trip to Tokyo. The room was very clean, a little on the small side compared to American standards, but probably sizable to Japanese standards. The executive lounge has great views of the city and a nice variety for breakfast. The staff at the desk in the lounge were very helpful with my needs. The concierge was also very informative. There is not too much in the immediate area of this hotel, but they do offer a shuttle to the Shinjuku station which is very convenient. There is a 24 hour market within a 5 minute walk which is great for grabbing a snack. This hotel is what you would expect from a Hilton, but because it is Japanese the service is a step above.

Got a room for $223 booked two days before departure, good price for a hotel like this in Shinjuku. Got a one bed room with a King size bed, with a size comparable with those in US, such as Hilton Arlington close to DC. If with two double beds, it would be a little crowded. Excellent beding, good supplies in the bathroom. Very clean. Friendly staff. There is a shuttle leaving every 20 min to/from Shinjuku station. Got a breakfast/internet package for 40,000 Yen (original about 52,000 Yen). The selections for the breakfast are very good, even if you are only interested in cereals. If you want to save money, walk several blocks to the east, there are plenty of options, local stores as well as convenience stores such as 7 eleven or Family Mart. Those convenience stores are different from those in US. They provide good choices at good prices for fast food and drinks of good qualities. Can be heated at the store. This hotel is about 20-30 minute walk from Meiji Shirine. There is a small park, Shinjuku Chuo Park, close to the hotel. However, it seems to be the home for homeless people. It forms a big contrast to other scenes in that area, but will fill a gap in your full impression of Tokyo.
