I asked a friend from Tokyo where to stay, and she recommended near the Skytree, as it would be quiet, not too expensive and have a great view. Reina's place was exactly that. It is out of the main tourist stretch, but is 5 minutes walk to combinis, a supermarket, and Oshiage Station (this is a non-JR line; the closest JR station is Kinishicho Station, about 18 minutes away). Within 10 minutes of walking, you can find quite a few restaurants nearby, as well as Tokyo Solamachi and the Skytree. There are thoughtful extras provided, such as converters, umbrellas, bathroom essentials, cotton tips, and makeup pads.
The skytree is visible from the main window, and the view from the rooftop is absolutely lovely. We only caught it at night, but I think it would make for a great sunset or sunrise viewing. The only negatives I can think of is that the bathroom is a little small, and that there is no elevator.
