What does the hotel concierge mean?

Hotel concierge is a department belonging to the front desk. The main task of concierge is to receive guests. When the guests arrive at the hotel, the concierge should take the initiative to open the door for the guests, take their luggage for them, and lead them to the front desk to check in. When guests check in, if they need concierge, they will also help them deliver their luggage to their rooms. Receiving mail and parcels, preparing cars for guests ... is also the work of the concierge.
