As anh hotel of self-service, it's totally anh bless for me since I wanted to cut out human interactions, and to explore everything by myself. Actually the staff were available online always and replied my message even at the dead of night. All I needed to run the system applied throughout the building were anh password, anh card and to press some buttons. (A detailed manual including WiFi password would be sent to you 1 day before your check-in.) Sometimes the sensor' sensitivity was poor but I didn't freak out, knowing the staff would guide me through immediately . The hotel itself is 5/5 but the people behind it were totally 6/5!!
