The Dormy Inn in Hatchobori appears to be an older building. The interior in the upper floors (where the rooms are) is drab and echo-y. The rooms are outdated. The double room was surprisingly large, although I heard the singles were very small (which is typical). The bathroom was also typically tiny, but it was in good shape. The real problem was that the room hadn't been cleaned well for some time. It was very dusty in the corners. The western style beds were also very hard.
That said, this hotel has several redeeming factors that almost made me give it a 4. First, breakfast was quite good. There was a wide array of Japanese breakfast items as well as western style food, such as waffles. They also have a very nice onsen. This was my first onsen experience, and I was a little nervous about the whole situation. However, the locker room area was very clean, with some nice toiletries available for use. They also had laundry machines in the onsen area (I think the washers were free.) The shower area was clean. The larger indoor bath was too hot for me, but the bath area is attractive. I didn't try the smaller outdoor baths, but they looked nice. The best surprise was the free late night ramen snack. This was very welcome after a very long day of exploring. I'm not sure what I was expecting, but what I got were fresh cooked-to-order noodles and delicious pork. More of a meal than a snack!
The hotel isn't located in a particularly exciting neighborhood, but there is a train station and some restaurants nearby, as well as a grocery store within walking distance. Actually, the area is really nice for wandering around on foot, as it's very close to the Chuo Bridge and Sumida river.
I can't speak to the value as this stay was included as part of a tour package.
