Well, you also have HotelDescription JPA entity, right? So you can define bidirectional mapping for entities.
instead of
@Column(name = "description")
private HotelDescription description;
you should have something like
@OneToOne(mappedBy = "hotel", cascade = CascadeType.ALL)
private HotelDescription desc;
and on the other side, in HotelDescription you should have back mapping
@OneToOne
@JoinColumn(name = "hotel_id")
private Hotel hotel;
When you will extract Hotel entity, JPA will also fetch child entity (HotelDescription) for you.
if you want to use @OneToMany mapping it will be (many descriptions for one hotel)
@OneToMany(mappedBy = "hotel", cascade = CascadeType.ALL)
private HotelDescription desc;
and on the other side
@ManyToOne
@JoinColumn(name = "hotel_id")
private Hotel hotel;
In JPA you can use several types of mapping like OneToMany, ManyToMany... That's only basics. Find a tutorial. You may start here: http://docs.oracle.com/javaee/6/tutorial/doc/bnbqa.html (not the best one probably)
Oh. And make sure you annotate id with @Id
