We stayed there 2 nights with my wife and our 5 months old baby.

The location in Taito was really ideal. It's a calm place with Akihabara and Oueno park at a walking distance!
The appartment size was perfect for the 3 of us. But the layout is a bit strange since its actually 2 appartments combine together in a U shape(so you have 2 bathroom, 2 entrance for a small apartment). The shower and hot water is tricky.
If good location is what your looking for. This is the place!
