1. convenient = close to Akasaka Station exit and a relatively big 7-11 is right next door; however, its a bit distance away from the main Akasaka busy zone.
2. Cleanliness = old style room layout with aged furnishing. the only complaint is the bed spread cover is very dirty, but underneath the bed are clean. Bath is clean.
3. front desk = so-so service, clerk is not what you would call "friendly" (for non-Japanese speakers).
