Many HTML elements have a default margin setting. You can override this and set it to 0. In your case, you want to reset margin-right on the radio button:
<input type="radio" name="beds" value="1" style="margin-right: 0" />1+
You probably want to add it to your stylesheet so that it applies to all radio buttons:
input[type="radio"] {
margin-right: 0;
}
