yes but leave out the article "a". what you wrote is fine but in a mercian english we say "this place is paradise"

He disappointed me. This place is a paradise. Guess what I'm making? I'm gonna make a popsicle.

There are two possibilities for the first sentence depending on what you are trying to say. 'He (has) disappointed me' or 'He is disappointed in (or at) me' which has a similar meaning to 'I disappointed him' This place is Paradise. It could also be with the indefinite article, this would subtky alter the meaning with the imlication that there are other paradises as well.

He is has disapointed me. This place is paradise or this place looks like paradise. I am going to make a popsicle for myself. Hope this helps.☺
