[Dx-qsl] EA7ADH address?

[Don Novy]

  I worked CO8LY and found 3 different addresses for
his manager, EA7ADH.

  QRZ.com lists     Francisco de la Serna
                    P. O. Box 1
                    Utrera - Sevilla
                    Spain

  Buckmaster lists  Francisco de la Serna Martinez
                    Cristobal Colon 36
                    41710 Utrera - Sevilla
                    Spain

  IK3QAR lists      Francisco de la Serna Martinez
                    calle Cristobal Colon 28A
                    41710 Utrera - Sevilla
                    Spain

  Does anyone know which address is preferred?
