We stayed at this hotel for seven nights. The room has a desk and chair, which was helpful for us. It is a bit cramped once you have two large suitcases, but sufficient for our needs, and probably actually bigger than a lot of other hotels in Japan. A wired internet connection was available as well as a TV with basic channels. Plenty of power points/outlets as well, which was great. The room was clean and tidy, and even when we did not wish to have the room cleaned, the maids still kindly left a package of new towels outside our door. The buffet breakfast is almost entirely suited to Japanese tastes, which was fine for us, but if you're not a big fan of Japanese breakfasts, it would be better to avoid it.
Be aware that while the hotel is upscale and professional, it is situated in an area with some "love hotels", which makes the area a little seedier than others. However, the train station is only about a 5 minute walk away, and is on two of the major Tokyo train lines. Only one stop from Ueno station, and a few more from Akihabara. VERY convenient!
While the hotel and staff do make some effort for non-Japanese speakers, the hotel is not really all that foreigner-friendly. The hotel room book (the one with services, information, etc.) was entirely in Japanese. In the laundry room, the washer and dryer instructions were also entirely in Japanese. (I would not recommend the dryer anyway, as it is VERY weakly powered and you cannot change the settings. It took several HOURS for one load of laundry to dry). At one point when I went to the front desk and asked (in Japanese) if the staff member spoke English, the person simply said "no", and that was that. However, at other times there were staff that did have some English - it was kind of hit and miss. If you have no Japanese skills whatsoever, you may find it a bit difficult.
Overall, we would probably stay here again, because of the value, cleanliness and proximity to the train station.
