Room was spacious and clean.
Equiped Kitchen was very convinient.
Toilet room and Bathroom are separated, it was very convinient too.
Staffs are very kind and professional, they are not hesitated to answer to all the requests.
Location was not great, but you can get to Suitengumae station in 5-8mins, and Kayabacho Station in 10-15mins.
Some review said it was very convinient there is a city air terminal just across the street, but there was not 1000yen bus. The rimusine fee was 3000 yen, so if you want to take a 1000 yen bus, you should move to Ginza station.
