NaNa's apartment sits alone at its floor, no other neighbors in the same floor. So you could own views to the city and to the riverside park.
It is spacious, with three twin beds and one sofa bed, and well equipped. Close to Asakusa Temple and easy to find. Nana also response fast and willing to help.
The huge TV in the living room also added some kudos, especially after a long walk in the city.
All in all it's a nice apartment to stay.
