If you are new to Tokyo it's fairly essential that you can get to your hotel (from Narita) using the hotel limo bus services as other public transport can be a bit mind-blowing the first time you experience it. This is the only downside to the Dai-Ichi Seafort - the limo bus runs a limited number of times each day to this part of the city. But if the times work for your arrival departure flights it's perfect. (Having said that, if you are coming in on an internal flight from elsewhere in Japan it couldn't be better as it is located on the fast / frequent monorail service which comes from Haneda domestic airport.)
Rooms are a reasonable size, well equipped and spotlessly clean. Excellent value via Expedia at £55 (Pound Sterling) per room per night. All staff without exception were typically Japanese (i.e. efficient, friendly, helpful). Views from the rooms are great, especially if you are on the bay side of the building - looking at the Rainbow Bridge. The bar on the 28th floor is nice (although expensive) but doesn't have much better views than your room unless you are on the "wrong" side of the hotel.
The food court in the base of the tower block gives a great choice for places to eat - and even Guinness on tap in the Irish Pub!
Transport links are limited but once familiar with the ticket machines, getting into, and then about, the city is easy and EVERYONE we met was helpful. If you look like you are lost / confused someone will stop and ask if you need assistance.
Highly recommended.
