The location is great, very near to Hibiya station with many subway connections. Also, very close to Yamanote JR Line, may be around 200 meters to Yurakucho station. The small road is full of restaurants, Izakayas, and convenience stores.
The apartment is on the 3rd level, note that there is no elevator. It over looks train lines, which is quite nice actually, once in the bedroom, it is not that noisy. So you look out the small balcony, you would see trains go by all the time, look down then you would see business people walk by, stopping for food and drink at all these restaurants. The apartment also has small cooking area, however around the place, you probably would not cook since again there are too many place to eat already. The bath is great, sit down shower with wooden bathtub. There is also a washing machine with drying so you can wash your clothes and dry at the same time. So for this location, and space that this apartment provides, for me, especially with the washing/drying machine, this was a nice place for me.
Overall very nice place, will come back again.
