Iriya seemed to be a quiet area. Although not central, if you don't mind walking a bit Ueno, Asakusa and other areas are accessible by foot, otherwise Iriya station is 10 minutes by foot.
Basic accommodation but it is clean and comfortable!
The only downside is the walls are thin so I was kept awake by the person in the next room coughing and talking on the phone etc.
Overall I was happy with my stay here!
