This hotel is below par. Heavy tobacco smell everywhere, including the "non-smoking" room. Half of the restaurants are in the basement.
I'm afraid it's anecdotal but this is an example of how cheap they can be: They offer a "breakfast included" deal but then they charge an extra 700 Y when I order cereals + fruit plate + yoghurt!
I travel to Tokyo every month and I usually stay at the Royal Park which has splendid restaurants and... a great breakfast. Too bad it was sold out this time.

As a world traveler you see some of the worst and the best. Some of the staff certainly goes out of their way for you and shows that they will try to use the rules to your advantage, on the other hand there is the Dai-ichi.
At 300$ a night you expect top notch service and at least some English, the Dai-ichi had neither.
Being that this hotel was on personal I was really excited and had high expectations...
The first day I had a do not disturb sign on and got called and woken not once but twice trying to schedule cleaning.
Then finally when we had an agreed time to get the room cleaned they showed up an hour early.
On the day of checkout they expected a 100$ additional fee to check out late even though it was new years and would do NOTHING to be flexible. The front desk staff had very broken english at best, the consierge was rude the only redeemable quality as the bell people who went out of their ways to make up for the main staff.

My wife and I spent 7 nights at the Dai Ichi Tokyo and had no regrets. The staff were outstanding, waiting to help you on anything. The concierge was very helpful and gave us great tips to get to Kamakura for a day trip. The Airport Limousine Bus stops at the Hotel so getting to/from the airport was easy. It is right next (connected via underground walkway) to the Shimbashi train station which has all three major train companies stop there (JR, Tokyo Metro and Toei), so you could take the JR NEX from Narita to Tokyo Station, then the JR Yamanote Line to Shimbashi. You can get to anywhere easily from Shimbashi. There are a ton of places to eat near by (try the stand up sushi bar a few block south, Miyako, both of us ate till we were full, with beer only $40 USD!! There is a 7 Eleven a block away that takes US ATM cards so getting cash was easy. Ginza is just a few blocks away (eat at the yakitori places under the train tracks near the Sony Building in Ginza, cheap and very good). The room was large by Japanese standards and bigger than some US hotels I have stayed in. The bathroom was huge with both a shower and a deep tub to soak in. We were on the side of the building that faces the train tracks, you can hear them but it never bothered us. Did not eat in any of the hotel restaurants or have room service, both were expensive (comparable to a nice hotel in the US). With so many great cheap places to eat near by you don’t have to. The only down side was there were only 5 channels on the TV. 2 were English (CNN International and BBC news) and the others were Japanese, although one kept showing the same program about an all women theatrical/musical group. I had wanted to watch some of those crazy Japanese game shows, but the available channels did not show any. Also they still use an actual key instead of a card key. That did not bother us, but thought that was unusual as even cheap hotels use card keys now. We would stay there again asked!!!

On a side note we were very intimidated by the train/subway system before we got there, but once you use it a couple of times its so easy to get around and is so efficient and cheap.

Reserved via the hotel website and was quite surprised our room included breakfast! 3 places to enjoy the morning: 1 at the 2nd floor of the hotel where there is a breakfast set of eggs (even eggs benedict which is fabulous), bacon or ham or sausage (singular because you get only one), breads, veggies like spinach, potato, cherry tomato, broccoli. Usual coffee, tea. 2nd option at the Japanese style next door to the 1st breakfast place - we only ate there once. 3rd option is the breakfast buffet but you have to cross the street to go to the annex and walk down some steps to get there.
But in my opinion, nothing beat the english muffin on the eggs benedict. I had it 4 mornings out of 9.

Room: same as other reviewers' opinions. You can hear the train but it's just a low rumbling noise.

Yes train station is very near but in the end we just took the taxi to Tokyo Station to get to the Keio line to get to Disney & Makuhari Messe (which was where the Tokyo Motor Show was).

Great Yamanote line to get to Odaiba which we went there twice. Get the day pass. We also did the Onsen there. great experience. Be ready to bathe in your birthday suit in the separated public areas though. But there are common areas where you get to go around in your yukatas or robes.

Highlight of out stay is this great little steak place called Steak Hanamasa. From the exit where the train tracks are, cross the road & turn right. It is right across a place called Almond. Great great steaks. It's a vending machine type place. You go in, put some money in the machine & press your order. The 900 yen steak is very2 good. We also ate there twice. Too bad we discovered it 2 days before we were to leave Japan.

Another great place across the street is a place that starts with a W. Wakame or Watami or something. There's a small rectangular pond outside. The food is very nicely presented & very good too.

Mt. Fuji tour by Grayline, sadly is ok but at the start they were very late. it says you have to be at the lobby by 9 AM. then grayline buses started coming but no rep to guide us. I found them standing outside. We left at around 930. The next day, same tour but now the reps went inside to go to the waiting tourists. My goodness. Maybe we just had one of those days..... But the day excursion was ok. it's a tad warm in Tokyo but when you get up to Mt. Fuji, it turns cold & windy, so bring extra jackets.

Can't wait to go back to Japan!
