The first question would be how old is your apartment? Currently this outlet would require GFCI protection. If your apartment was built before the code edition containing the requirement was adopted by you municipality it wouldn't require it. Also, there is a possibility this outlet is protected from the load side of a GFCI receptacle in the other part of the house or a GFCI breaker. Are there any GFCI receptacles in the apartment at all?
