Great value for money. Host gave clear check-in instructions. The unit is complete with everything you will need, but can get a bit cramped for a small family when you consider the luggages. The building has an elevator so it was pretty convenient for us since we brought a stroller.
As to the neighborhood, it's maybe a 10-minute walk to Kinsicho Station which can get you pretty much anywhere you want thanks to Tokyo's vast network of trains. It's near love hotels but it was generally peaceful, not much people around. We traveled with a young child and we always felt safe even at night.
Near convenience stores, malls/shopping areas, and Life Supermarket which closes late, perfect for a quick grocery run before heading back to the unit. Try the Ikinari Steak restaurant.
