One of the best place we might have during Japan trip across 5 cities. Not just clean, but (relatively) close to Toei and Metro. Even you can walk to Asakusa for minutes. There is also elevator and english speaking staff.
The best part is, there is big supermarket (not convenience store) within 1 minute walk, open until 12 PM where you can get everything. Definetely will recommend to our friends who plan to visit Tokyo.
