There are many things to do and see nearby. We stayed with our three kids. There was enough room in the house and several playgrounds nearby. We could walk to ueno and skytree in about 45 min. The walk to the subway was about 15-20 min with three young kids.
The bathtub is short (I couldn't stretch my legs out) but deep and if you know how to turn it on it can stay hot! One of 12 nights we were there a police siren/car went off and scared my kids. It's not a busy street, but I could hear the odd truck go by. The windows are single pane. Also, there are bars on the windows and the glass is opaque, so if you want to look outside it's best to open the front door. Overall we had a lovely stay.
