'Haven' is a word rich in connotation, suggesting shelter and security and peace, and adding this to 'home, ' another word with highly favorable connotations, multiplies the effect. The last line, 'Sandalwood, cedarwood, and sweet white wine, ' is, in my opinion, one of the most pleasant sounding lines in English poetry.
