user14288: I have noticed that it seems Nibbana has been described as "the peaceful". 
I have had the impression that Nibbana is neither joyful nor delightful.
Is my impression correct?

user14104: On Nibbana

"This is peace, this is exquisite — the resolution of all fabrications, the relinquishment of all acquisitions, the ending of craving; dispassion; cessation; Nibbana."

— AN 3.32
Its essentially peace within your being  .In Your experience of joy or sadness you are detached meaning not possessed by the experience .It doesn't mean that you are indifferent or passionless but truly alive ,cooperating with the experience ,being with the experience ,where there is nothing but experience ,ceasing to cause anything or interfere in your life process, because with every need to cause there is nonacceptance of an experience .Thus in Nibbana you simply are .
Its important to realize that you don't view Nibbana as a goal that your ego needs to achieve You don't gain anything from Nibbana because you become empty from all your conditioning and your ego with all its accumulations disappears.You let go of all the attachments including that of the body, you let yourself happen like you let a flower bloom.

user16632: Yes.
Whatever word you use to describe it, it will miss the mark, as Nibbana is free of concepts, perceptions, judgements, etc. If you label it "peace", that is based in your perception of peace, which cannot exist at Nibbana. If you label it bliss, that too misses the mark. It may be more accurate to say, "after the experience of Nibbana, I felt supreme peace and bliss of an otherworldly magnitude", etc. Nibbana is, by it's nature, nearly impossible to describe and conceptualize. Like a black hole, it is only discernable to the normal mind by the things surrounding it.
It may be more useful to learn how to experience it than to wonder too much about it, which may engender expectations and concepts that you'll have to let go of eventually anyways. ;)

user254: AN 9.34, Ven. Sariputta says (in translation) ...

nibanna is bliss

... and that what's blissful about it is that there are no "feeling" i.e. vedana.
The word translated "bliss" is sukha.
The word translated as "joy" is (instead) usually piti and associated with meditation (and impermanent).

user295: OP: I have noticed that it seems Nibbana has been described as "the peaceful".
Nibbana is peaceful of blissful because it is not dependent on sensations/feelings.
The whole Shere of sensation regardless if it is present, unpleasant or neutral is unsatisfactory (dukkha).

pleasant feeling is pleasant when it persists, painful when it changes;
painful feeling is painful when it persists, pleasant when it changes;
neutral feeling is pleasant when there is
knowledge of it, painful when there is no knowledge of it.

Cūla Vedalla Sutta
OP: I have had the impression that Nibbana is neither joyful nor delightful.
In terms of sensations, this is not pleasant, unpleasant or neutral. But since is it not dependent on the sensation it is not unsatisfactory.
