Location wise, it is super strategic. It is just a few minutes walk away from subway ( DT line ), 1 station away from Shibuya where lines converge ( You can take express bus to Fuji area from Shibuya too ), 4 stations away from FutakoTamagawa where you can do all the shopping you need without the crowd, 1 hour away from DisneySea and Kasai-Rinkai Koen. There are plenty of nice cafes, ramen places, Izakaya, restaurants and parks within walking distance too.
The place itself is nicely decorated. It has amazing amenities like clean towels of all sorts, hair dryer, remote controlled varying intensity and colour lighting system and super-responsive water heating system. It is however located at the first floor by a main street, so you can't quite open the curtains. Other than that, it is one of the best places to stay for exploring Tokyo.
