doorkeeper

A doorman (or doorwoman/doorperson), also called a porter in British English, is a person hired to provide courtesy and security services at a residential building or hotel. They are common in urban luxury highrises. At a residential building, a doorperson is responsible for opening doors and screening visitors and deliveries. They will often provide other courtesy services such as signing for packages, carrying luggage between the elevator and the street, or hailing taxis for residents and guests.
