Input Element Causing Errors - class

Question

My class is currently studying Classes and I'm attempting to complete my assignment due tomorrow. I have most of it done, however, for some reason the address input won't let me input any letters only numbers.
I can't figure out what I'm doing wrong here and would appreciate help in figuring out if I need to change something.
#include <iostream>
using namespace std;
class personalData
{
private:
string name;
string address;
int age;
string phNumber;
public:
void setName()
{
cout << "Enter name: ";
cin >> name;
}
string getName()
{
return name;
}
void setAddress()
{
cout << "Enter address: ";
cin >> address;
}
string getAddress()
{
return address;
}
void setAge()
{
cout << "Enter age: ";
cin >> age;
}
int getAge()
{
return age;
}
void setPhone()
{
cout << "Enter phone number: ";
cin >> phNumber;
}
string getPhone()
{
return phNumber;
}
void displayData()
{
cout << "\nName: " << getName() << endl;
cout << "Address " << getAddress() << endl;
cout << "Age: " << getAge() << endl;
cout << "Phone: " << getPhone() << endl;
}
};
int main()
{
personalData person1;
personalData person3;
personalData person2;
person1.setName();
person1.setAddress();
person1.setAge();
person1.setPhone();
person1.getAddress();
cout << "\n";
person2.setName();
person2.setAddress();
person2.setAge();
person2.setPhone();
person2.getAddress();
cout << "\n";
person3.setName();
person3.setAddress();
person3.setAge();
person3.setPhone();
person3.getAddress();
cout << "\n";
cout << "Person1 details: ";
person1.displayData();
cout << "Person2 details: ";
person2.displayData();
cout << "Person3 details: ";
person3.displayData();
return 0;
}
Here is what it looks like if you input both numbers and letters:
And here is what happens if you only input numbers:
