Great place, and cheap also! The location is very good, right next to Ueno and Akihabara and easy Metro access to anywhere you would like to go in Tokyo. The host is very kind.
Regarding the noise between rooms, there was only one other person in the first night I stayed here and that wasn’t so bad because the person was also quite respectful/quiet at night. For the worst case case Minami has ear plugs provided in the rooms, so you should be fine!
